The nut being my cousin Rick.....a total fitness nut who had a heart attack and subsequent quad. bypass 2 years ago at the age of 46.  Still had trouble and needed a pacemaker this past winter.  He won't give up.  He's participating in a triathalon or however you spell it this Sunday.   A mile and a half swim; a 24.8 mile bike race and a 6.2 mile run.  I hope he survives it.  It's supposed to be in the mid 90's in Huntington Sunday.  He read where he and Dick Cheney have the same ejection fraction....whatever the heck that has to do with his decision. I think my husbands E.F. is about the same, and he's not trying to prove anything to anyone. Rick's the one with the peacocks and turtles and stuff.  I always love new stuff to worry about.
