I think that when one approached the winter of life, thoughts turn to missed opportunities and things to try. The goal is so that at the end, there are no regrets. I would hate to say to myself "I should have tried xxxx." or " I should have fucked that cute redhead that worked at the quick-e-mart" Dying with regrets would be miserable. I have got to get busy living life.
I have my own list of things that I want to experience before the ability and opportunity to do something about it is gone forever.
What's on yours?
