It is quite understanding that every individual get older day by day and as we get older our power and strength and ability also reduce, which natural affected our output. Due to this poor output is what brought about retirement age, generally there is a particular age that we are weak as humans and cannot do some certain work.

Retirement age also in need and useful to implement in every organization so that the weak ones can give ways and opportunities for the young ones and youths to be replaced. It is a chance given previlage for the young ones,  I think retirement age for workers makes sense in my own view and little understanding.
