As your youth fades further into the past, you may start to fear growing older. But research shows there's also very good reason to be excited: for many of us, overall psychological functioning actually peaks between ages 55 and 60.
This highlights why people in this age range may be at their best for complex problem-solving and leadership in the workforce. In contrast, humans reach their physical peak in their mid-twenties to early thirties.
A large body of research also shows that people's raw intellectual abilities – that is, their capacity to reason, remember and process information quickly – typically starts to decline from the mid-twenties onwards.
This pattern is reflected in the real world, where athletes tend to reach their career peak before 30.
