My body composition is not too different from yours. I have a little less fat and a little more muscle. I'm also 6' 0" which makes it difficult to fill out. I'll get around to taking a pic.
Btw, I expect a prize for guessing your height (off by an inch or so).
Also, your room is a mess and that's quite upsetting.
I won't call you short but will say with certainty that, based on other posts by you, it all makes sense now. Everything about you.
