Skinny girls look good in clothes, curvy girls look good in bed

I think it is all about how one carries their weight. If you take care of yourself then you can reasonably expect to look fairly healthy, but when you add other factors in aging such as sickness, cancer treatments, etc and if you are already thin your skin is going to be hanging more.

Because they're idiots?

I don't know that is true, don't think adding weight when they are older makes them look any better.

Because people judge, and feel the need to be heard on, everything?

Don't listen to people who love to label people's skin.

Really thin people don’t look good ever.
