I read the rant and the retort. I have my own unique take on it. From old military days and mind/war games to bouncing and bodyguarding to now marketing in radio for 25 years, I've learned to recognize a reaction similar to the primal 'fight or flight'.
The male creature much more often than not responds to things they are ignorant or fearful of with faux anger, often laced with weak attempts at humor or irony. Stafko is a large, unfit man with a type of Napoleonic complex. He can't be you or beat you, so he'll attempt to berate you. Rather than admit ignorance and learn, his tact is to defer from him to you. He's the bully on the playground who's the frightened kid in reality. The frat boy who still calls a beer a "brewski" long after the last kegger, and he is in loathing of himself.
Suck it up buttercup, from one fat bald old guy to a younger fat boy, better to be a moving target than a bump on a log. Grow some stones rather than throwing them. Lace up a pair of sneakers, struggle through a 5K and finish dead damn last, but feel the honest rush of knowing you finished it and no one can take that away from you. Back away from the buffet big boy, you'll find a lot of athletes willing to share, teach, cajole and love you into being more than a bitter self hating asshat. Phew! Was that a B.A.R.? And as an aside, Fartleks still make me giggle.
