Geneva: Certain psychological factors such as quick thinking and feeling healthy may be very strong predictors of how long we will live, a new study has found. Researchers from University of Geneva in Switzerland and University of Oxford in the UK examined 29 years' worth of data collected from 6,203 adults who ranged in age from 41 to 96 years old when they began the study.

Aggregating data from 15 different tasks, researchers looked at participants' cognitive performance across five domains of ability - crystallised intelligence, fluid intelligence, verbal memory, visual memory, and processing speed.

The tasks - all well-established measures of cognitive ability - were administered up to four times over a 12-year period, allowing researchers to assess participants' baseline performance and change in performance over time for each domain.

The results showed subjective health and mental processing speed to be two of the strongest predictors - that is, better perceived health and smaller decreases in processing speed over time were associated with reduced mortality risk.
