The era of diesel cars is here...

TO BUY or NOT to BUY?

Humans have depleted black oil in an exponential rate faster than it can produce naturally.  Some predicted that there will not be any black oil after another 100 years.  With no gas for cars, other forms of energy are needed to power up our transport vehicles.

Electric cars are the main stream of replacement and there are many effort put in place for innovations.  If you visit LTA website, you will notice that Hybrid (aka Petrol-Electric) cars are gaining market share in Singapore.  But the cost of owning a hybrid car has little incentive but the cost is exorbitant.  It is nearly a prestige to own one.  Can the savings offset the premium of hybrid car?

If you dig further, you notice that Peugeot 2008 1.6 e-HDI EGC active car running on diesel has a mileage of 3.8 L/100km (Combined).  This is way better than an old car running at 9.0 L/100km.  With the pending retirement of 30% of the car population in Singapore due to expiry of 10-year COE, it is a good time to consider all options: To buy or not to buy?

OPTION 1: BUY NEW CAR

If you want to buy, you may wish to get the best deal.  Here, we will review only the petrol costs of ownership in the next 10 years.

Petrol or diesel is expected to increase over the years and on average, we predict that the price may increase by 50% in the next 10 years.  This is a logical presumption based on the petrol price in 2004 is S$1.50/litre and now 2014 is US$2.20/litre.

The choice is whether to get one running on petrol or diesel.  The next question to ask is whether to get a hybrid or not.

OPTION 2: EXTEND COE

You may also opt to extend the COE of the current car if it is still in mint condition.  However, in view of the high COE, it is not a great option now.

GAS COSTS FOR 10 YEARS

The estimated gas consumption for 10 years are:

1. Old car (1.6 litre extend COE 10 years): S$32,116.50
2. New car (1.6 litre petrol): S$24,979.50 (Saving: 22.22%)
3. New car (1.6 litre diesel): S$11,970.70 (Saving: 62.73%)
4. New car (hybrid on petrol): S$ 13,560.30 (Saving: 57.78%)
5. New car (hybrid on diesel): S$ 11,094.80 (Saving: 65.45%)
6. Electric car:: S$5,897.80 (Saving: 81.64%)

Interestingly, if you choose diesel cars, the saving on gas is more than 50%.  If you choose hybrid on diesel, you will pay S$11k instead of S$33k.  Really? Why? What is the trick?

There is no tricks.  Just make sure you choose an efficient car that RUNS ON DIESEL.  Why?  Because you will save S$20k in the next 10 years.

If you can afford, get a hybrid car running diesel.  Peugeot 2008 (S$117k) is one of these diesel cars.  In LTA website, only 3 out of top 40 gas saving cars run on petrol.

For electric option, the new 2015 Volkswagen e-Golf and Fiat 500e consumed only 2.02 litre/100km (US Environmental Protection Agency aka EPA).  In short, you will pay only less than S$6k instead of S$32k over 10 years factoring inflation on gas prices.  A hidden cost is the battery depreciation which warrants a change every 3 to 5 years (same for hybrid cars).  The biggest headache is there is no way to charge your car battery in Singapore...yet.

OTHER WAYS TO SAVE COSTS

There are also other costs involved which you may wish to read further HERE.  You may choose to take a cab instead of buying.

Alternatively, you can change your driving behaviour and learn from Wayne, who clocked 59 MPG or 4 litre/100km on an old Accord.

The economy of taking taxi

Introduction

Taxi is hailed as the most expensive personal transport for those who do not own a car.  It is deemed impossible to book during peak and shift changing hours and costs a bomb for long distance travel.  In this tiny island, there are 6 taxi operators fighting for the slices of market share with demand always outstripping supply.

Mobile Apps

With the emergence of taxi apps such as GrabTaxi, EasyTaxi and Uber, there is simply no turning back now.

Conventional booking methods adopted by taxi companies are outdated and could not cope with the demand of the customers.  I have personally waited 30 minutes on my mobile and still there is no taxi available as informed by the operator.  Perhaps, the operator is the bottleneck as well as a cost factor.

Mobile app connects the customer to the taxi driver directly and eliminates the middleman.

Supply of taxi

More importantly, mobile apps also do not restrict customer to a particular taxi company and broaden the choices of the customer. In particular, private cars under Uber can respond and indirectly UberX forms the 6th "taxi company".  To consumers, more is always good as choices are available to meet demand.

From another perspective, taxi drivers can wait for bookings instead of circling round and round to hunt for prospectives thereby saving petrol.  It is a win-win situation.

Consumer Experiences

The satisfaction from customers is the ultimate measure of whether the services are good.  By having more choice, direct messaging and contacting with the driver, real time tracking of approaching taxi, cashless payment and the ability to give ratings on the drivers complete the entire service evaluation. By the conventional method of calling for cab, it is always a one-way traffic and there is hardly any feedback loop unless you lost something or the driver is nasty.

Cheaper taxi fares?

Uber claimed that there is a 25% savings if you book UberTaxi.  We managed to get an actual case of UberTaxi during off peak period clocking a distance of 23.91km and a trip time of 24:55min.  The charged fare is S$20.62 which is 19.1% cheaper than normal cab rate (S$24.58).

Another saving can be the booking of premium cab for short distance of less than 12km.  The standard rate is S$38 for less than 4km or S$50 for other distance.  Using UberExec, a short distance of 6km costs only S$22.10.  This is especially useful during peak hours and normal cabs are hard to come by.

Extra goodies

GrabTaxi offers GrabCar (6) and GrabCar (13) which can accommodate more than 4 passengers.  This is particularly handy when we wish to move in group and booking of multiple taxis is a co-ordination nightmare.

EasyTaxi has the lowest booking fees of only $2 during off peak period and like all 2 mobile apps, provide cashless or credit card billing services.

Uber has an ongoing promotion which gives $10 for one-timer.  Enter promotion code uberdear can instantly give you $10 to try out their service.

Conclusions

It is exciting to look forward and guess what these companies are offering.   We have yet to try out MoobiTaxi, Split it, Come Fetch Me, Taxi Monger and Taxi Booking.  They are new comers and are looking for their pie of the cake in the taxi industry.  To consumers, it is always good news that more mobile apps are available to offer choices for us.  Perhaps, the best is yet to come.

Cheapest drive to Johor from Singapore

From 1 Oct 2014, the toll charges in Causeway have increased and it is no longer economical to drive to Johor Bahru town centre.  The traffic is still crowded during peak hours but one thing is certain: no one with a sound mind will drive in just to pump petrol or take a meal especially he is alone.  Having said that, it is still worthwhile if the car has 4 or 5 passengers to share the costs.

Straits Times reported that there is a saving of 30% incentive (S$9.40) to use the second link (http://www.straitstimes.com/news/singapore/transport/story/second-link-traffic-likely-increase-higher-causeway-tolls-kick-201409).  However, the maths just simply does not add up.  Perhaps it is a misunderstanding on their part or they listen to the wrong advice.

One may wonder which option is the cheapest to drive to Johor now with second link thrown in.   Below chart can be your reference:

From the table, you will save S$1.50 by driving to Johor via Second Link and return via Causeway.  By factoring the petrol costs and possible toll charges between the 2 destinations, the net saving may vanish altogether.

The Malaysian authority has accurately priced the toll charges in Causeway in anticipation of Singapore's move to equal its tolls.  In general, it costs S$11.50 to 13.70 to make a round trip.

Singapore and Malaysia Tolls

470% Toll Hike for Class 1

Malaysian Highway Authority (LLM) announced all vehicles (including Malaysian cars) passing through (Bangunan Sultan Iskandar Customs, Immigration and Quarantine (CIQ) will be paying a higher toll charge from 1 Aug 2014.

For sedan cars travelling to JB and back to Singapore, the hike is 468.97% (RM2.90 to RM16.50).  The breakdown is RM9.70 for inbound and RM6.80 for outbound.  Malaysian cars are no exceptions.

Currency	MYR					S$	%
Class	Old (inbound)	New (inbound)	New (outbound)	Total New	Net Increase		Increase
1	RM2.90	RM9.70	RM6.80	RM16.50	RM13.60	$5.33	468.97%
2	RM4.50	RM14.70	RM10.20	RM24.90	RM20.40	$8.00	453.33%
3	RM6.10	RM19.70	RM13.60	RM33.30	RM27.20	$10.67	445.90%
4	RM1.40	RM4.80	RM3.40	RM8.20	RM6.80	$2.67	485.71%
5	RM2.30	RM7.80	RM5.50	RM13.30	RM11.00	$4.31	478.26%

Malaysians who travelled to Singapore to work daily and drive back to sleep are heavily slapped on the new hike.  If you are not aware, the morning queue into Singapore at both customs are very bad as many Malaysians are rushing in as early as 4:30am.  Some Singaporeans who have relocated to Malaysia are also commuting into Singapore to work daily.

Another increase coming: Vehicle Entry Permit (VEP)

The above toll charges are not to be confused with VEP, which is only meant for foreign vehicles (such as Singapore cars).  Since Singapore government has announced the new VEP rate of S$35.00 for non-Singapore vehicles entering into Singapore, Malaysian government has not fixed the price yet.

Coming next: Eastern Dispersal Link (EDL) Toll

At the moment, EDL is still free for use.  EDL is useful for driving direct to KL or nearby cities bypassing the crowded Johor Bahru city area.  So far, no toll has been announced but it is always on the chart for extra income.  Even Malaysians are confused why the new toll hike is presumed to supplement the construction of EDL in 2003.  Let's wait for more details.

Conclusions

So far, it seems S$5.33 increase (Total: S$6.47) is still affordable for many Singaporeans.  With the 3/4 fuel tank restrictions, either you stop going in or you can just buy and eat more to make up for the S$5.33 toll before you pay more to drive into Malaysia.  Once the VEP details are clearer, we will update the new rates for reference.

JB for petrol?

Update: The latest changes on the new Toll Rates for Johor Causeway effective 1 Oct 2014 is reflected in the calculation.

50% cheaper?

Did someone tell you that Malaysia's petrol is at 50% discount as compared to Singapore?  It is as attractive as the Great Singapore Sales (GSS)!!!

With this belief, many are faithfully and patiently queuing up driving north just to top up petrol believing that they are saving money especially when the exchange rate is at Singapore's favour.  Especially now with S$1 = RM 2.61.

Indeed, petrol is termed as the black gold and the world's supply of petroleum is now lower than the world's demand.  Though Singapore is a world famous refinery centre of oil, the selling price of petrol is more than twice of its neighbouring countries.

Unfortunately, this may not be true if you check your wallet at the end of the month, the saving may even be LESS. Why?

Worth or not?

While you stop and move in jams when coming back to Singapore, have you wondered if it is worthwhile to drive up just to pump petrol and back?  Are they worth the 3 hours (inclusive of dinner) you spent in jams?

Every cars are different but the transport costs are similar:

1. Travel from home/office to JB and back still consume petrol for the car.  If you stay in Woodlands, consider yourself lucky but for those who stay in Changi, you are paying more to drive to JB;
2. Costs of tolls in both Singapore and Malaysia customs (PLUS card).  For second link, you have to pay again when you are driving back to Singapore;
3. 3/4 tank legal requirement for Singaporean vehicle driving out of Singapore; and
4. Fuel efficiency of your vehicle plays an important part especially if you are caught in jam.  With engine and air-con running, petrol are still being consumed even if the car is at a halt.

So there must be a purpose if you wish to drive north for petrol else the cons might outweigh the pros.

Classic examples

For instance, Alex (blog: http://loganized.blogspot.sg/2011/05/pumping-petrol-in-malaysia-how-much-do.html) was surprised that he had a saving of S$3.13 for a May trip in 2011.  If you look closely, he is gaining virtually nothing as he failed to factor in the toll charges imposed by both customs (~S$2.50).

If he wasted 2 hours in the jam, there is literally no saving if we factor in the depreciation of the car and its parts in the long run. There are many who have similar experiences and continue to drive in like Alex.  Are you one of them?

Some employed tilting of cars in attempts to pump more petrol (URL: http://www.sgwayoflife.com/forum/viewtopic.php?f=3&t=1536).  It claimed that pump attendants said the total saving is S$1.30 to S$2.20 for small/mid cars and S$4 for MPVs.  Is this working for you?

In Perspective

Instead of guessing and listening blindly, it is good for us to know what are the actual savings we have if we just go JB for petrol.  We are pleased to offer you a one-time offer to calculate your savings by entering your details below.

Please give us 3 working days to get back to you as we are not working full time on this blog.

SSD vs HDD – Why you should choose SSD over HDD for Win7?

Before you buy i7 and the best graphic card in the market, read this.

I know desktops are dying and are currently being replaced by tablets and mobile phones.  But I believe they will last for another 10 years as they fill the vacuum between server and mobile phone where we need reasonably strong computing power and a big screen comfortable to the eyes.  On the side note, in the long run, I predict many youngsters will develop arthritis, wrist/thumb issues and short sightedness as they relentlessly try to “break” the Corning’s gorilla glass while playing their game or replying messages.

Coming back to the topic, costs for desktop are dropping dramatically and it is realistic to buy a desktop (without a monitor) with a budget of S$600.  If you have a comfortable budget for S$1,000, then you must consider adding a Solid State Disk (SSD) into your system to remove the biggest bottleneck of any computer.  I also strong recommend this if you wish to upgrade your notebook hard disk.  Let me share the generic advantages of SSD:

1. Withstand shock and vibration because there are no mechanical parts.  For a notebook, it implies you can drop notebook on the floor and your data is still intact;
2. It saves power consumption as it draws only 1 Watt instead of 6-8 Watt (quite little as compared to 300 Watt video card);
3. You enjoy faster startup or boot up speed; and
4. Most importantly, your computer works faster.

How fast?  Is SSD worth it?

If you are getting a low-end or budget PC, forget about SSD.  But if you can chalk up S$1k, why not spend another $150 to speed up the slowest component of your desktop?  The question is how fast?

If you take a standard 7200rpm HDD versus a low-end Intel X25-M SSD, you can see that SSD outperforms HDD in all aspects especially in random read speed.

	HDD (Mbps)	SSD (Mbps)	SSD over HDD (times)
Sequential Read	77	260	3.38
Sequential Write	80	107	1.34
Random Read	0.7	64	91.43
Random Write	0.8	48	60

Now, sequential is useful for transfer, copy or move files of large size.  The faster the sequential speed, the shorter you wait.  Three time faster means time saving and you can feel it in real time.  For operating system, the key indicator of a responsive system is RANDOM WRITE.  SSD performs 60x faster so it is significant in real world.

All you need for a SSD is put an operating system (like Windows 7) into it.  If you install a new Windows 7, you will notice you need approximately 12GB of space.  However, Windows will grow due to its reserved space, restored point or buffers over time.  You may also add frequently used applications for faster speed.  Buffering what you need, you do not need 128GB or 240GB SSD.  If you tap on cloud storage, 30GB or 40GB is sufficed.  You can add 1TB or 3TB as additional storage.  For notebook, you may want a bigger SSD as there is only one slot for 2.5” HDD.

What take the trouble of getting small SSD?  The reason is simple – SSD is expensive.

Dell has an article about why they find SSD is too pricy and they offer no SSD online in Singapore.  NAND flash pricing has dipped significantly over the years since the invention of usb drives and the popularity of iPhone, iPad and all NAND flash devices.  The price point may remain stagnant due to the loyalties of the flash inventors as there is a minimum price point they are looking at.  But the higher capacity flash will definitely be cheaper in the long run or the patent expires.

Web-Feet Research has been following on the trend of SSD and below is the summary:

Cents/MB	2004	2005	2006	2007	2008	2009	Diff
HDD	0.139	0.111	0.091	0.077	0.06	0.04	71.2%
SSD	34.7	18.6	9.6	5.1	2.6	1.2	96.5%

*: Prediction

From 2004 to 2009, SSD’s pricing fell more than HDD’s.  Still bigger HDD can never win SSD in any performance tests.  So SSD has the unique selling point – better user experience.  No tweaking or optimizing of any HDD can outperform a budget SSD.

Okay. What is the catch?

SSD has limited write cycles and frequent writes will kill it faster.  Getting a SSD with trim working under a supportive operating system (ie Windows 7) which optimizes and recognizes SSD is important to prolong its life.  Preventing excessive writes in SSD is also important so disabling restore point and saving files in C drive etc will definitely help.

After you have used SSD, there is no turning back or regret.  I promise.  All your programs are running in steroid mode!  With SSD, it is faster with i5 over i7 (without SSD).  Vice versa, the fastest graphic card cannot remove the bottleneck the HDD inherits.  So get a SSD rather than i7 or the fast graphic card.

If you have some time or extra cash, you may like to pair 2 SSDs in RAID 0 for a 10 sec boot up.  Meanwhile, download SSD Tweaker for easy configuration in Windows 7.  Do share if you have other tips on SSD.

iPhone 4S Craze?

I have not been posted for a while due to other commitments.

The first post will be iPhone 4S. Since Steve has just passed away and he is missed by many, it will be a good time to see if Apple has products to continue his legacy.

There are minor updates to iPhone 4 but 4S has breaking sales due to the demise of Steve. What are the interesting features which many found it useful? Some of the features are:

1. Siri - a voice app that aims to be your personal secretary;
2. Speed - dual cores which nearly double the benchmark and chipset is upgraded to A5;
3. Camera - 5 element lens and 30% improved sharpness on a 8MB resolution with video stabilization; and
4. iOS5 - new OS with special mention of iCloud which promises 5G storage space in the cyberspace.

The question to ask is whether iPhone 4S breaks new ground or people just buy it for the sake of remembering Steve. Industry is disappointed it is not iPhone 5 but the sentiment defy expectation and sales better iPhone 4.

How is competition? Samsung Galaxy S2 is the closest competition with the chart HERE. A complete comparison is spelt out HERE in iTechVision. Numbers aside, the question is do you want to upgrade if you already has iPhone 4?

For those without data plan, it is a punishment to buy a iPhone 4S if you do not understand the true meanings of mobility and smartphone. Those who have already owned a iPhone 4 with a budget, it is not advisable to upgrade as the features are not fantastic. You can save for an iPhone 5. Apple is cashing in on Steve's death and maximise their profits.

If you never own a smartphone before, you may consider iPhone 4S. But before you jump into the wagon, spare a thought for other smartphone vendors like Samsung Galaxy S2 or Nokia N9. Both are cheaper than iPhone 4S and your experiences will not be dampened as long as you have a data plan (the key to your smartphone experiences).

You have lots to learn if you have your first smartphone. The key is the applications which you can install to suit your lifestyle with a data plan. In the world of social media, instant communication is the key to be hype. Getting a fad iPhone 4S with no data plan will be the biggest mistake you will make. Given limited budget, get a smartphone with data plan is better off than an expensive iPhone 4S with no data plan.

Frankly, technology gadgets are fads when the warranty is only 12 months for a 24-month standard mobile contact. The costs of the "free" phone has already been included in the monthly payment. When the warranty expires in 12 months, you are still paying for another 12 months for the discounted phone but enjoy no warranty for another 12 months. Isn't it interesting?

In Amercia, Apple's iPhones are tied up exclusively with AT&T with a cheapest US$15/month data plan for only 200MB of data. As a new customer, you are expected to pay another US$399 for a 64GB iPhone 4S. Bear in mind that the data speed is inconsistently low at a maximum of 2.5MBps at best with repeated upgrade on its networks.

In Singapore, Singtel's customers are expected to pay S$39.9/month for a 24-month plan for an upfront cost of S$798 for a 64GB iPhone. A new Samsung Galaxy S2 I9100 and Nokia N9 16GB cost S$148 and S$98 respectively. You do your maths.

For a die-hard Apple fan, you may consider the old iPhone 3 or iPhone 4 as they have depreciated to a "free" phone. The argument that Apple fans has is Apple provide long-term support for its handset while other vendors ignore their older phones when they have new models. Very true as we see iPhone 4 can be upgrade to iOS5 while many Android phones are still in Froyo 2.2 or below instead of the latest Gingerbread 2.3. In fact, non-Gingerbread phones are often sold at discount or free to consumers with a budget to clear stocks. Manufacturers offer no upgrade on its firmware and obsolete them before the 24-month mobile contract is over. It is a sad fact in the industry. Apple wins hand down in support since they have only a handful of mobile phone sets. Read more by The Understatement.

No matter what you choose, stocks for Samsung Galaxy S2 and iPhone 4S 64GB is low now. With plenty of stocks, Nokia N9 is the underdog as Meego OS may be obsoleted soon as the partnership with Microsoft thickens. The only merit of N9 is the free OVI GPS map where the download of maps is free.

Afterall, it is a Laissez-faire ecomony and the choice is yours.

Increase in Electricity rate

UPDATE: Click HERE to download the file for easy calculations.

Household electricity consumption

I have covered the topic on how to measure your household electricity bill in my last article in May 2008. Since then, SP services never fail to increase electricity tariff for four consecutive quarters. Starting in April, our new rate will be 23.56 cents/kWh or an average increase of $2.47 in our monthly electricity bill in four-room HDB flats as reported by Straits Times. The latest reason cited is the increase in oil price over the past three months from US$99.38 to S$102.95 per barrel.

Ranking of power hungry household appliances

The best power saving method is NOT to switch on anything. We know it is impossible so how can you maintain or reduce your electricity bill? Identifying the most power hungry appliances and reduce its consumption is the best approach. Below is the typical list:

Ranking	Household Appliance	Power Consumption (W)
1	Bathroom Heater	2000
2	Induction Cooker	1200
3	Cloth Iron	1000
4	Water Boiler	750
5	Air Conditioner	600
6	Rice Cooker	500
7	Fridge	200
8	Desktop PC	160
9	CRT TV	135
10	Fan	60
11	Notebook	55
12	Light bulb	40

 
As a rule of thumb, appliances that heat up or cool down in the shortest time consume the most power. Bathroom heater tops the list with 2000W of power consumption while light bulb only consumes 40W. Appliances worthy of mention are Induction Cooker, Cloth Iron, Water boiler and Air Conditioner which are power hungry. To get a realistic feel of how much they are consumed, we need to know the hours of usage to get the monthly bill.

Household Appliance	Power Consumption/ unit (W)	Hours of usage/ day(Hrs)	Monthly Bill with GST (S$)	Ranking
Bathroom Heater	2000	1	15.13	3
Induction Cooker	1200	1	9.08	6
Cloth Iron	1000	0.5	3.78	8
Water Boiler	750	0.5	2.84	10
Air Conditioner	600	8	36.30	1
Rice Cooker	500	0.5	1.89	11
Fridge	200	24	36.30	1
Desktop PC	160	8	9.68	4
CRT TV	135	9	9.19	5
2 Fan	60	4	3.63	9
Notebook	55	4	1.66	12
3 Light Bulbs	40	5	4.54	7
Total Electricity Bill			134.01

 
After punching in the average consumption per day, we get a realistic power consumption of the appliances. Fridge and Air-Conditioner top the bill charges while notebook tails behind. To effectively cut down on the bill, we explore how to reduce the usage time of the appliances. Bear in mind that basic necessities such as fridge cannot be touched. Below are some suggestions:

1. Use fans instead of air conditioner;
2. Cut down on using Induction Cooker and use gas instead;
3. Reduce the frequency of using bathroom heater;
4. Iron cloth every fortnight. FYI, heating up the iron is very time consuming;
5. Refrain from using water boiler to keep warm and use vacuum flask instead;
6. Adopt standby or hibernation mode for breaks exceeding one hour; and
7. Sleep early so watch less TV programs.

Household Appliance	Power Consumption/ unit (W)	Hours of usage/ day(Hrs)	Monthly Bill with GST (S$)	Ranking
Bathroom Heater	2000	1	15.13	2
Induction Cooker	1200	0.25	2.27	8
Cloth Iron	1000	0.05	0.38	12
Water Boiler	750	0.25	1.42	11
Air Conditioner	600	3	13.61	3
Rice Cooker	500	0.5	1.89	9
Fridge	200	24	36.30	1
Desktop PC	160	6	7.26	5
CRT TV	135	6	6.13	6
2 Fans	60	12	10.89	4
Notebook	55	4	1.66	10
3 Light Bulbs	40	5	4.54	7
Total Electricity Bill			101.47

 
After changing the consumption pattern, only fans cost more due to longer period of usage. If the fridge is your top list, then you have near to your target. Revised bill is $101.47 which is a 24.28% reduction in power consumption.

Conclusions

There are some devices (S$150) sold in the market which promise to save your electricity bill. The basic operation is to optimize the inductive and capacitive powers (correcting the power factor) which exist in any power supply due to different appliances used. This is especially useful for Air conditioner, washing machine and other inductive devices. In Singapore, the effect is noticeable for 5-room flat or bigger units but less significant in smaller HDB units. Suppliers claim that the savings vary between 5-25%. If you are interested, please attend computer show as they are always participating in such shows. Watch out for mini-sun or power save booths.
Now, you can save your pocket money and environment at the same time and preserve a greener earth for our future generations. I must talk big because cutting back on what you are currently enjoying is painful. Trust me…
