@ Senpai - So thin people tend to be more affected by cold or heat? That makes segments in snowy area's harder. Is Japan usually cold or warm?
Side note - At least you have muscles
I was thin to the point where I couldn't run without my pants falling down and I don't even excercise. Got a high metabolism from my parents. Also, that's your twin? You don't really look alike
My older sister and I had the same facial structure when I was younger.
