Well, as usual the rules make no sense -- there was some random cut-off weight that didn't take height into consideration.  I think it was 105 lbs. or something like it.  This was back in the early 80s.  I got a letter asking if I'd donate blood to replace the blood I'd gotten in transfusions.  Attached was a list of rules including the weight restriction and no donating if you'd had blood transfusions.  I haven't even bothered trying since.

Damn, I thought I was skinny.  That's friggin' skinny.
