Thanks, all.
The genes are mixed. Yeah, Grandpa only made 67, but my dad is 92.
Of course, only one other Gerlach has lived that long; made it to 97 - but Dad says he doesn't count, because the last 5 years all he did was lie in bed & drink a quart of rye whiskey every day.....
On Mom's side, pretty much no one dies younger than 85*, though; average it out and i see a good chance of 90. Though, how I feel now, i'm not at all sure that's a good thing, ya heard?
*I discount her cousin - closer to my age - who wrecked his CB750 on the way home from a party about 19 or 20.
