Something funny seems to happen to me when I'm stressed; I suck at Chess.
My Chess rating for Blitz games drops when I am stressed. Blitz games are Chess games with fast time control. I usually hover between a 1500 to 1600 rating when I am on fire and confident about life. When stressed, I hover between 1300 to 1400.
While anecdotal to me this all proves that stress eats a lot of our brain cycles.
Chess is a game of logic and strategy; there is almost no chance or luck involved, like in other games such as Poker. The better player will almost always win in Chess; it's why supercomputers can always beat humans at Chess now.
There were a few times where I didn't even realize how stressed I was, and a consistent losing streak in Chess was the only clue.
When I start getting destroyed in Chess, it's a real eye-opener that I am stressed. It means other thoughts consume my brain cycles, and the game of pure logic and reason becomes nearly impossible at a high level.
This begs the question about people's performance in other high-stress environments. Such as interviews or other settings, I wonder if we are getting the best out of them?
Are you performing your best by being stressed out?
