This is perhaps the most difficult answer I've seen since I came here.

The truth is that there isn't a definition for the best time for one to die. No one likes the idea of dying even at Old age. In think the only people who would contemplate dying are those who have painful illnesses or ailments that makes them suffer.

The only time to me when death would look like the best choice is when one gets that feeling of fulfillment, that everything that one needs to achieve has even fone already.

This could come at any age whether at thirty or at eighty.

However, even after fulfilment, some would still prefer two remain to see how things are would turn out, how people would react to their achievements.

So, for me, the best time for one to die is when the lifespan that one was created to live for has elapsed.
