I don't know. Maybe it's just our different subjective look on it, I'm not arguing just to argue, it's just my opinion. I'm not saying you or any other post-LL patients will have a reason to worry about their proportion, that's all individual and can vary based on body types and all sorts of stuff. And I certainly don't think Obama has short legs, but I don't think they're unnaturally long in relation to his upper body either for an african guy. About those two latest pictures, in the one he's clearly a little up on his toes because he is being hugged. He also seems to be wearing some sneakers probably giving him more height than normal dress shoes or flats. Also, in both pictures, that kind of jacket hugging around the waist makes everyone's legs look longer because of the contrast between the jacket and the pants. I have a similar jacket and it always makes me think my torso looks shorter than it is, making my legs look long. Same effect if you tuck in your shirt in certain pants. If you look at where his butt ends and imagine him sitting down revealing his sitting height, I don't think his legs are unusually long at all. I think if we measured his sitting height to standing height ratio it'd come out pretty average. Again, for a guy his ethnicity. Studies on that ratio show caucasians and asians having shorter legs on average. So maybe that means they can get away with closing in on the ratio of africans.
About CM Punk, his legs look long(er) with those boots, agreed. But wrestling is an image based performance sport. The audience will accept quite a few out of the ordinary things about the fighters' appearance. I've never seen the guy before but I immediately thought of it more as a gimmick. I think his fans thinks his higher up knees are because of those boots, and it's also emphasizing the part of the legs below his knee because they're black and creates a contrast. I guess like me the fans "accept" seeing his long legs because he's wearing those boots. I don't know if anyone would think it looked normal if he was like that barefoot. Either way, look at this picture, I don't see his legs as very long at all there. He looks normal and proportionate. Yeah, he's wearing a huge belt, but it's easy to imagine where his torso begins.

Now there's always the question if anyone not aware of LL will notice, and much can be hidden by clothing. But of course there's nothing wrong about Obama's long-ish legs. He's a black guy with normal proportions and he hasn't done leg lengthening.
