I still rock at Kaboom. My spider senses still work as good as ever.
Studies have shown that after peaking at 24 years old, reaction time declines between 4 and 10 milliseconds per year, depending on the type of activity measured, where constant and fatiguing decision making (such as in a RTS game) amounts for 10 milliseconds per year decline, and isolated tests amounts for 4 millisecond per year decline. This means a person who is 34 years old is between 40 and 100 milliseconds slower than his/her 24 years old self. Reaction times can be improved by good sleeping, eating and exercising.
