I have to admit .... he used to be very pudgy at a time when I
was ripped and six-packed, (sigh, glory days, only in pics
now ... ) ... but something happened in his poly days, I suspect
probably some girl's rejection .... and now he's got a long
distance runner's body while I ............
not as ripped as me as I was in my hey day though ... 
Go forth and train yourself to be a long-distance runner then.
