When I was a teenager playing Starcraft, I learned that one of the guys who regularly played with us was in his 50s. At the time it seemed weird anyone that old would be able to keep up in this game, or even know what it's about.
I find lots of players in Overwatch are surprised to find I'm 46 with an above average SR whenever it comes up. Though I typically don't snipe, I seem to still have some twitch reflexes left!
