I agree with you that the fear of aging comes when life has not been fully enjoyed and one is not satisfied.
Of course it's also true that I think everyone would like to live forever, at least I would like to, I like life too much.
However, we must accept that our time will come to an end and it is useless to think about when or to worry, we only waste time and energy that we could devote to better thoughts.
Nice post!
I liked your comment because you are absolutely right, we have to accept that our life is finite and that way we don't waste energy on it.
