Proud to say I got all 25. And I don't mean I thought about a few of em and decided "I can probably do that." No no. I have either done or had training in all those.
Heinlein's list is better though, and I don't have all of those down yet. Although I am reminded of my friend "Jeff", a lifelong white-collar boy of unsurpassed self-assurance, despite readily available evidence to the contrary. Case in point: I once handed him a post-hole digger and told him to dig a hole "right here" until the digger sunk up to a tape mark on the handles, which would make the hole about 42" deep. An hour and a half later, "Jeff" had a hole 2 feet wide and a foot deep, attempting to remove a soft-ball sized rock which was in the way of his hole-making progress. I smashed the rock to bits with one anger-fueled stroke of a heavy bar, and he continued his digging. He got to about 36" and went home.
I showed "Jeff" Heinleinn's list once, and he read it over and said "I can do all that stuff." Sure. He is a computer programmer by trade, so I'll give him that, but I have my doubts about the other 21 things.
PS. I haven't read Cooper's list yet. I am feeling pretty manly today and I would like to hold on to that.
