VPA for UPI
Virtual Payment Address for United Payment Interface for various services are given below (only few). 1. BHIM - @upi
2. Phonepe - @ybl
3. SBI - @sbi
4. United Bank of India - @ubi
5. City Union Bank - @cub
6. Google Pay - @oksbi, @okaxis, @okhdfcbank
7. Truecaller - Mobilenumber@icicipay
8. MiPay - @myicici
9. Airtel - @airtel
10. Paytm - @paytm
Among all UPI Apps, Phonepe is the best app for following reasons.
1. Short upi handle (ybl - Yes Bank Limited)
2. Multiple Bank Accounts and Money transfer between self accounts is made simple.
3. Now they introduced Phonepe Keyboard. This keyboard enables to check balance, send money and more through keyboard without opening app.
4. More apps (booking), redbus, irctc, olacabs etc.., located inside Phonepe. You can book anything with Phonepe app.
I created shortest VPA (Virtual Payment Address)

Put AC at 25+ degrees and put the Fan on at slow speed
Very useful information sent by an executive engineer from EB:
Correct use of AC:
As hot summer has started and we use Air conditioners regularly, let us follow the correct method.
Most people have a habit of running their ACs at 20-22 degrees and when they feel cold, they cover their bodies with blankets. This leads to double loss. HOW ???
Do you know that the temperature of our body is 35 degrees Celsius? The body can tolerate temperature ranging from 23 degrees to 39 degrees easily. It is called human body temperature tolerance.
When the Room temperature is lower or higher, the body reacts, by sneezing, shivering, etc.
When you run the AC at 19-20-21 degrees, room temperature is much lower than the normal body temperature and it starts the process called hypothermia in the body which affects blood circulation, whereby, blood supply in some parts of the body is not adequate. There are many disadvantages in long term such as arthritis etc.
Most of the time there is no sweating when AC is ON, so the toxins of the body can not come out and in the long term, cause risk of many more diseases, such as skin allergy or itching, high blood pressure etc.
When you run AC at such low temperatures, it's compressor continuously works on full energy, even if it is 5 stars, excessive power is consumed & it blows money from your pocket.
What is the best way to run AC ?? Set up Temperatures for 25 Degrees.
You don't get any benefit by first setting Temperature of AC to 20 - 21 and then wrap the sheet/ thin Quilt around you.
It is always better to run AC at 25+ degrees and put the fan on at slow speed.
This will cost less electricity and your body temperature will also be in the range and there will be no ill effect on your health.
Another advantage of this is that the AC will consume less electricity, the blood pressure on the brain will also decrease and Saving will ultimately help reduce the effects of global warming. How ??
Suppose you save about 5 units per AC per night by running AC on 26 Degree and other 10 lakh houses also do like you then we save 5 million units of electricity per day.
At the regional level this savings can be crores of units per day.
Please consider the above and do not run your AC at all below 25 degrees. Keep your body and environment healthy.

Central Government Water Committee Analysis
BATHING...... By Shower consumes 100 litres. By Bucket 18 litres.. Saving 82 litres. FLUSHING after toilet By Flush is 20 litres By bucket is 6 litres Saving is 14 litres. WASHING CLOTHES In a running tap - 116 litres In a bucket .. 36 litres Saving is 80 litres. SHAVING In a running tap..5 litres In a mug .. 0.5 litres. Brushing Teeth In a running tap..5 litres Closed tap or Bucket .. 0.75 litres. Washing Car In running tap water nearly 100 liters....... white with single bucket 2 to 3 cars can be washed with just 18 liters....... Watering Potted Plants In running tap water nearly 50 liters...... Bucket less than 10 liters.... Watering Garden Running tap 100 lites or even more in multiples...... sprinkler system only 25/ 30 liters Please Use Bucket n You will find a notable difference.. Choice is yours whether to enjoy n be safe with municipality / bore well water or disturb your family health by calling tankers water. Each family can save atleast 300 Liters of water per day with minor changes in life style...... 💧Please Help Save Water.....💧 Help Save Ur Future...... 🙏🙏🙏 Save Water Please pass this message till it reaches everyone in the world🙏🙏🙏 It is a wonderful message to save water for the future generations.
