Try this reaction time test: https://humanbenchmark.com/tests/reactiontime

200 is the mean, 273 is the median. I'm 21 and I average anywhere between 160-180ms depending on the time and day, but I have a low-latency setup. The best of the best can get down to 140-150 average.

I'm 61 and average 211. I don't think my reaction time is bad, but my memory isn't as good as it once was.

I have 398 so not very fast. Still I do great in CS :)
