Pops look at it this way. Granted on my mom's side most of my family is relatively healthy and not overweight. I met my dad at 16 and we recently hooked back up on Facebook. That side has all kinds of health issues.
I look at it as though I had a good run. I ate good, drake good, and kicked it hard.... Now I still do all that but in heavy moderation.
I was never big , but a sedetary(sp) job and not watching what I ate added pounds to the kid. Never been a big eater, never liked buffets or upsize just ate two many calories in my three squares.
Man just do what you're doing and slurge on occation. All that kicking back eating good,drinking good will catch up to those folks later on in life..
