Seems to me one should live each moment in the certainty that they will die, and they don't know when that time will come. It also seems that the "mystery" surrounding the when of death is a great motivator to make ones life have meaning. Or it can be a motivator of other things as well. Isn't the maturation process all about the knowing that ones life is passing? I guess I am taking the long way around to saying that I find the passing of one's life to be an incredibly interesting experience, and I find the certainty that the end is closer than the beginning to be an incredible stimulus to seek to understand as much as I can. Add to that the uncertainty of "when?", and it almost lends a zest to the quest. Do I want to know when? Nope. Do I care? This is less and less important as time goes on.

All the best,

Mick
