@Green Witch,
And my skinny cousin bulked up in the rangers, but the bulk was all (or seemed all) muscle..
I haven't talked to him lately, but it seemed from here that his experience in the rangers was beneficial for his maturing/development, despite or maybe somewhat because of his being in the gulf war forefront, and despite some personal woes of his. I was anti gulf war, feeling a bit lonely in that at the time, so I'm not pro war as a way to mature and get muscles - but those things coincided.
On the thread argument, I get why M. Obama said what she did in paraphrase, saw the list of all the military personnel who signed up on the issue (I haven't searched past what I see on the thread), think her comment could have been worded better, if only about the numbers: 25% or 40%, the numbers weren't all due to obesity; just that a majority of the medical refusals were due to that, if I read things correctly.
