I used to get so worked up in the heat of the moments that I had to stop playing and let my heart rate come back down in the upper 90s....
I'm not quite there yet. I'm only 51, but that's one reason I'm more into the bomber flights than fighters really. Not really up to the heart stress and definitely don't have the reflexive responsiveness I used to in tough dogfight situations. Back in my 30's when I LOVED flying my favorite Yak fighters at the time (only the 9U and 9T were available), I could mix it up pretty well with opponents. Not so anymore, sadly.
