Wearing Seat Belts in cars became compulsory on 31st January, 1983. I do not know of any country where seat belts was prescribed as legal requirements before 1983. It is not that the concept of Seat Belt was new. Seat Belts had earlier been used for flights ever since commercial aviation began. However, when the manufacturers of the aircrafts were confident that once in the air the seat belts could be removed, flight instructions were accordingly modified.
Nowadays, once again, it is recommended that during the flights passengers should continue to keep Seat Belts fastened. A Seat Belt to me is a symbol of caution and care you need to take while doing anything which is not devoid of risk.
But there is nothing worthwhile that can be achieve without taking some risks. In fact not talking any risks in life is the biggest risk.
So, to grow and progress in life and experience happiness of success, you need to take some risks. But always wear Seat Belts. Ensure that you take all possible precautions - that is wear Seat Belts and go right ahead.
