Gee, that's funny. I don't notice it that much around Southern NH.
I myself am a whopping 155 lbs and ~ 5'11. Large boned and muscular (my family says I look like a twig). But I remember in HS, I was 220 lbs 5'8 for years, and in the afternoons consumed one large bag of Dorito's and one large bag of Combo's cheese crackers, as afterschool "snacks"...Plus I could easily polish off a large stuffed-crust pizza at Pizza-Hut all by my lonesome.
Dang man. People say I'm like an athlete, now! I take in 100 + grams of protein with less than 1500 calories per day. Only problem is, I don't have the strength I used to. But nobody that I know of has my endurance.
People need to be calorie conscious 24-7. I just got tired of being fat!
