There comes a time in everyone’s life when the brain and the body reach their peak before age begins to take its toll.
While muscle mass, strength, and function start to deteriorate around age 30, new research on professional chess players suggests the brain actually ages in a slower and more gradual way.
Analysing 125 years of expert chess games and tracking individual performances over lifetimes, scientists plotted a hump-shaped curve, a tiny little speed bump that stays true across various different generations of chess players.
Before a player’s early 20s, performance on the chessboard appears to increase rapidly. Skill then appears to reach a plateau around 35 years of age, peak at age 40, and begin to steadily decline after age 45.
Accounting for factors other than age, like the colour of chess pieces, the length of the game, the generation of the player, and the strength of their opponent, cognitive decline after age 45 decreases only somewhat and in a statistically…
