I'm on a beta blocker and had to have stress test a while back. Fuckers worked me over on the treadmill to even get my heart rate up enough where they needed it to take the pics.
So then why does my heart rate go nuts hiking up the mountain Elk hunting? I know, altitude...
But yea, if some lard ass like me or bigger that doesn't cardio (57YO 5'10, 225#) is passing, they're cheating.
