You can measure your reaction time here: https://www.justpark.com/creative/reaction-time-test/
A bunch of people at my work tried it, I was the fastest at 50 years old in the 240ms ballpark consistently. How do you score?
Reaction time is a lot slower than I would have thought! I read that our auditory reactions are about 30ms faster than visual ones due to the simpler processing pipeline. A pinball travels about 4"-5" in a quarter of a second if it is going 1 mph.
