I get pissed off when people say "I hate running" "it hurts my knees" "marathons kill people" "running ruins your body" "it's so booooring" and all the other excuses that even humans have started to believe.  We're de  4237  signed to run mother fucker, get off your lazy ass do it.  You have to be running 6 minute miles, trod along at 4 mph or jam out at 10 minute miles.  It doesn't matter the speed, just go!
