Is a drummer a musician???
More so than billards and maybe the equal of bowling.There is a winter Olympics event called "curling." Are the curlers athletes?
I'm sure that every single medical type person would say that an unconditioned person with a heart rate of 180+ for an extended period of time is at considerable risk for a myocardial infarction.
Athletes?
Absolutely!
