It's pretty weird because, even though I completely believe y'all when y'all say you get comments, but I have never ever had comments directed to me by a stranger about my weight.  I am approximately your size 5'9" 145 lbs and BMI 21 & not that swole. I live in Canada though, I don't know if that makes a difference (maybe we're too polite to comment)... I'm still waiting for it to happen to me!
