Research-backed guides on reaction time, reflexes and cognitive performance — written to answer the questions our tests raise.
Average Reaction Time by Age: What Studies Show
Aging costs about half a millisecond a year — less than a bad night of sleep. The cited numbers behind the adult average, the real age bands, and what actually moves your time.
Read the guideWhy Reaction Time Matters in Sport, Driving & Daily Life
Milliseconds decide more than games: how reaction time shapes sports performance, driving safety and long-term brain health — and the proven ways to sharpen yours.

Every test on this site raises the same questions: what does my number actually mean, how do I compare, and can I get faster? This blog answers them properly — with the published research behind reaction time, attention and the senses, not with invented leaderboards or made-up averages. When an article states a figure, it cites the study it comes from, the same rule the rest of the site follows.
Expect practical guides on what a good reaction time looks like at different ages, how sleep, caffeine and training genuinely affect your reflexes, why sound beats sight by a few crucial milliseconds, and what tests like Go/No-Go or the F1-style start lights really measure. Each guide pairs with a test you can run in your browser — read the theory, then put your own reflexes on the clock.
