That's because it was exceptionally rare. I was one of 2 or 3 fat kids in my high school (don't worry guys, it was over 20 years back and I got my shit together as soon as I left home). Even though I was fat I was "only" 190lbs, 5'9" male at my heaviest. Now that weight is considered a small fat for a 5" femayo. It's crazy how much we've declined as a society in such a short time.
