Several friends of mine did complain about the issues of being mid-sized - they always stink.
I've grown to slightly mid-sized before and it's terrible. I just can't look myself in the mirror. Twice in my life I got to that because I gave up on exercise. As soon as I got back into martial arts and sports I lose most of it off.
Mid-sized women are also not my favourite. My ex was pretty much her size at the peak of our marriage. She had many health issues that she put off which could've been fixed if she stops overeating.
