Moving answers, and I can identify with some better than others. Age is really a state of mind. When I was younger I might have thought about doing the Captain Oates bit, but with time I`ve come to know that Life is the most precious thing in the universe and not to be thrown away under any circumstances. We learn from experience and I`m a firm believer in going through a door when it opens in front of you. In years I`m 72 and just embarked on my 4th marriage.
I`ve been studying the afterlife for many years and I try to learn from those wiser than I am. As someone said, death is not to be feared rather to be looked forward to as an exhilarating moment and the lead-up years to it, whether they be less pleasant or not, should be learnt to be accepted. All happens for a reason.
