And in my experience, having gotten into fighting games in a serious way for the first time at age 30 (I'm now 37), people tend to attribute atypical "good reaction times" to what are actually smart input buffering techniques. In a crowd populated by mostly 20-somethings, I still routinely end up in the top 15% in a given game, and those opponents that beat me never feel like the difference was reaction time. Going from memory from a link I'll surely never be able to find again, so take this with a grain of salt, the US Air Force had a vested interest in studying how reaction times change as we age and found that it didn't really start to decay in any meaningful way until long after 40.
