I've been told that I look like I'd be good at sports too. Both of my sisters are, and we're workin with the same gene pool as far as build goes. I also have kind of a long neck and have been told that it makes me appear graceful or even tall (I'm 5'5"). I have a hard time with left and right still sometimes and I'm a grown ass woman lol!
Low Si makes sense. Just couldn't help but relate to you once again. We are not broken lol!
