I have to say I have more than just some experience here... Quick decision times decline VERY slowly; that is to say the amount of time it takes to make the correct decision as opposed to just reacting to a situation. You are confusing the amount of strength it takes to play at the top level and still have enough in the tank to not lose focus. FWIW I'm not talking out of my hat here, I "played" a very thought intensive sport in my younger day and was one of the top guys in the US on any given day. I still have ridiculously quick decision times and the concentration of a Monk with ADD when I drive, But there's no way my bod could compete with a my former self of 20 years ago. I'm in pretty good shape now but I'm not a World class athlete anymore.
