What the NFL does: playing catch with pads on!
(For the record I'm a big fan of NFL, long time Green Bay fan)
More straight edge talk: Ironically giving up fizzy drinks (soda) would be the hardest thing for me to become straight edge. I've been properly addicted to caffeine at least 10 years, I try to stop every now and then and I last 3 days at best before I'm drinking coffee by the pint. Alcohol, drugs even meat would be a breeze but giving up my tasty cola beverages?! With that in mind I actually have a lot of respect for properly straight edge people (not just 14 year olds who give it up first time they're near booze) like CM Punk, it shows a strength of character to some extent.
