Average reaction time at age 72
A typical untrained 72-year-old averages about 369 ms on a simple visual reaction test — 119 ms off the lifetime peak reached around age 24.
Reaction time follows a U-shaped curve across life: children start slow, speed peaks in the mid-20s at about 250 ms, and the average drifts gently upward afterwards. Here's exactly where age 72 sits on that curve — and why the number is less fixed than it looks.
Age 72 on the curve
| Age | Expected average |
|---|---|
| 62 years old | 337 ms |
| 67 years old | 353 ms |
| 72 years old | 369 ms |
| 77 years old | 386 ms |
| 80 years old | 397 ms |
Placed on the overall adult distribution (mean 273 ms), an average 72-year-old's 369 ms is faster than about 5.5% of all adults. The comparison is a little unfair — that pool includes every twenty-something — which is exactly why comparing against your own age group matters more.
What's happening at this age
At 72, the expected untrained average is around 369 ms. The decline is real but often overstated — much of the measured slowdown in older adults comes from unfamiliar devices and caution (double-checking before tapping) rather than pure nerve speed.
Reaction practice at this age doubles as genuinely useful cognitive training: studies on processing-speed training in seniors show gains that persist for years.
How to beat the curve at 72
- Prioritise a familiar, responsive device — an old tablet with high touch latency can add 50+ ms and make the number look worse than it is.
- Play short and often. A handful of 30-second rounds daily is the sweet spot; fatigue shows up faster and costs more milliseconds than it used to.
- Train the general way that works at any age: short daily sessions, full attention, ten-round averages. The complete method is in how to improve your reaction time.
