(Some) timers can at least be learned, I can still instinctively time RA, MH, YA on Quake 3 tourney maps even after not playing seriously for about 20 years now

(Some) timers can at least be learned, I can still instinctively time RA, MH, YA on Quake 3 tourney maps even after not playing seriously for about 20 years now. It was something you learned. Reaction speed not so much, I recall taking tests years back and I'd clock in around 110-120ms reliably. Now, 160-210. I'm still playing fast-paced FPS predominantly so I don't think this is something that's going to come back to me. That said, I suspect age is less of a factor as physical condition and the long-term effects of moderate alcohol consumption.
