There appears to be a correlation between reaction time, IQ, and life-span.
By consistently practicing reaction time tests would it be possible to improve upon the bio markers for longevity?
The researchers learned that those with higher IQ scores lived longer, a result consistent with other studies. The study also showed that characteristics significantly related to death included male gender and smoking. But Deary and Der also found something new - faster reaction times seemed an even better predictor of long life than IQ.
I have been able to bring my average time down with some practice. Hopefully life expectancy can be improved by thinking faster
