While teenagers might have youth on their side when it comes to some forms of brain power, arithmetic skills are said to peak at around age 50. And although we might be fitter in our 20s, people are generally more content with their lives the older they get, with people over 60 reportedly having a better life satisfaction than those younger than them.

Still, the evidence which points to having an improved psychological wellbeing at 82 years of age can only be a good thing.
