I'm glad I wasn't the only one in that boat. Back when I was 30something, I was messing with an HRM and had done the basic calculation for my (then) max HR, which I think was in the high 190somethings. So I was hoofing it up a hill and watched the HR climb til it cleared the threshold and it started to blink (it's programmable). So I went at almost-full gas for a bit until the hill gradient backed off a bit and I dialed it back a bit, but I guess it was warm enough that I started getting the I-don't-feel-so-good feeling whereupon I decided to just stop, even though I knew what was going to happen. Sure enough, the blood rushed from the head (where does it all go?) and I knew I had to lie down on the road, head below feet to get that Ahhhhh feeling. It was all worth it because shortly thereafter a guy driving the other way stopped and asked if I was OK.
