Why do ENGINEERING students always prefer LOCAL AUTHOR books than REFERENCE books..?
The LOCAL AUTHOR BOOK says,
"Jack & Jill went up the hill to fetch a pail of water, jack fell down and broke his crown and Jill came tumbling after"
REFERENCE BOOK says,
Two humans ascended a certain geological protuberance to collect hydride of oxygen whose quantity is not specified. One member Jack of rapid irregular disturbing movements encounter fatal logical gravitational error leading to complete disarray. Other member whose scope lies within disarray descends down the geographical protuberance at an acceleration, whose magnitude is controlled by the force of gravity"
This is something which we are not focusing in our daily life but can produce multiple problems in spine especially for those who have long sitting hours. Make sure that when you sit in your office chair your wallet should be not in your back pocket(Not only Wallet don’t sit with anything in your back pocket).
Your wallet can be real pain for your back and the waist, and it can even lead to shooting pains down the legs. Sitting on a wallet for prolonged hours every day can compress sciatic nerve which passes beneath piriformis muscle and leads to piriformis syndrome, low back pain & self-inflicted sciatica.
The wallet acts as a wedge that forces the pelvis, spine and body out of alignment. Just as you would not sit on a brief case or a rock for an extended period of time, you should not sit on your wallet. Anyone who drives more than a half hour sitting on a wallet is a candidate for sciatica or back pain.
The healthiest option is to move the wallet to your front pocket. If it’s must to keep your wallet in your back pocket, you should remove it before you sit down.
