Posting that video right after those posts by Apo was pretty much the most epic burn I've ever seen since I started reading forums about LL. You delivered everything people have been asking him for, and then more. Beautifully "choreographed" video, I must say.
Also, pretty much an excellent post-lengthening showoff with everything from proportions in business attire to underwear and your (well above average) level of athleticism.
Your wingspan makes you quite lucky. I think if it was naturally equal to your height (which is statistically more common), your arms would be approaching noticeably short. They're not so now. You look more "leggy" than most guys in the dress pants with your shirt tucked in and in some positions it's noticeable that your knees are a bit high up. So primarily I think you shouldn't lengthen any more with regards to our lower vs upper body proportions. You don't look freaky or anything now, bit I think you could cross a few thresholds if you did more.
Now, what this DOES say is that when a person lengthens over his wingspan, and even more than you have already in BOTH segments, they most likely WILL look like a weirdly small upper body walking on stilts like a spider. Even worse if the person doesn't have broad shoulders and a big upper body build. Ironically this applies to a lot of genetically skinny and small guys below 5'6" so they have to be even more careful with how much they lengthen.
A thought hit me today, that for a "cosmetic" surgery, this procedure has very few proper visual demonstrations of the results, even from surgeons wanting patients. Or in Apo's case, even people wanting to promote it. Pictures and videos are few and far between. We've collected some in the old thread about it here, and in my opinion many of these look visibly abnormal even with not that much lengthening. The only surgeon who's been posting videos is Donghoon, and they seem more focused on showing off function (running) than whole-body proportions. I think the fact that most people can't lengthen more than 6-7 cm before they start looking weird in one or more way is among the reasons for it. In almost all cases it's going to be a choice between height and proportions. And every body has their limit for what's going to look "freaky".
Anyway, thanks a lot for these videos!!
