my old man was 82 when he passed.
every time he came over to my place, he would give a good look at my head and say : "HEE, HEE, HEE ! i got hair and you DON'T ! HEE, HEE, HEE !"
he sure seen humor in that. when he passed, he had a full head of hair. a little thin, but still had it on top.
i've had the "no hair on top" for a very long time. [got LOTS coming out my nose and ears though..... ]
