My right hip is noticeably larger than my left. Pretty sure this is because I grew up on a farm and used a pitchfork and shovel a lot during puberty and even before. The last 3 low back vertebrae of mine seem to be stuck and move mostly as one. When I walk I brace my knee for impact before heel strike, which gives me an interesting gait. I studied anatomy and movement patterns in school. I would be able to find little odd things about every one of you. We are all unique in some odd ways, and it can usually be explained by how you grew up and genetics. Gait analysis is a fun one to do.
Ugh my gait is totally uneven. My leg muscles are different sizes, I'm sure it's because of the way I walk. Thankfully it's the kind of difference that only the person who has it really notices. (You know, like when you stare in the mirror at that one thing you dislike about yourself and mentally magnify it so that you always see it, but no one else ever notices til you point it out?) I have been told I have a "cool swagger" though, which is...just because I walk funny. But none of us are symmetrical or even the same in the way we are laid out. It fascinates me, for instance, to think about how, while the body has a basic blueprint, it's more like a "Oh, this should go about here " than an exact plan. This usually comes up when I am looking at people's veins (when you can see them through the skin). Even on my two arms the layout is different, it is very interesting to think about everyone else's as well. Edit: OK, obviously, what I think about is also one of the many, MANY things that make me weird.
