Thanks to various studies, we have a good idea of when certain skills and physical capabilities—like muscle strength and facial recognition abilities—peak. Business Insider has compiled this information into a timeline.
Remembering new names: 22
Muscle strength: 25
Elite marathon running: 28
Bone mass: 30
Playing chess: 31
Learning new faces: 32
Making a Nobel-Prize-winning discovery: 40
Vocabulary: late 60s - early 70s
Psychological well-being: 82
Note, however, that these data all come from different sources, and some are more reliable than others. The tidbit about marathon runners—the average age to complete a marathon in around two hours—came from an analysis of 50 years of data. The peak ages for doing arithmetic and knowing vocabulary words both come from a study of 48,500 people. Meanwhile, Business Insider’s data point on the best age to marry—26—comes from a mathematical calculation on how many romantic options you can screen before all your prospective mates get married and drop out of the dating pool.
