Why it happens?
Even though it is known that the accidents do take place for the causes in our control, occurrence indicates the perception of the person involved directly or indirectly ignoring the safety principles.
Risk-taking is more in these instances.
Risk-takers may earn more in financial circles, but, the benefits are always negligible compared to one major injury that cripples our as well as dependant's lives.
Easier said than followed, still one should always go for a safe method that protects him and others.
