We got a call last night. My echo cardiogram was good. My four heart valves are behaving normally. Looks like I won't be leaving just yet.
I'm glad to continue on for a while. The countries of the world have assured me that they are prepared to carry on without me. My wife says that she too is willing to die, but that I had better not leave before her. Women, and indeed mammal females in general, are well known to live longer than men and males, but I intend to buckle down, bite the bullet, give it the old elementary school try, hitch up my belt, and pay attention to living long and right.
If I am good and I don't do anything stupid, if my luck holds out, if I don't waste my money, if I look where I'm going, if I don't drive too fast, I should last a while. Piece of cake!
