The human brain reaches its "cognitive peak" at the age of 35 and begins to decline after the age of 45, according to a new study.
At the age of 35, the brain is at its most powerful say Ludwig Maximilian University of Munich researchers.
Scientists studied thousands of chess games over a span of 130 years for the groundbreaking research, reports Mail Online.
The study looked at chess games over the years in a bid to understand how the brain develops through age.
During their research, scientists discovered a "hump-shaped curved" where cognitive performance increased sharply up to age 20.
From age 45 onwards, performance gradually declined, reports the outlet.
Researchers studies chess games from 1890 to 2014, where Uwe Sunde and colleagues analysed over 1.6 million moves.
The moves were analysed in over 24,000 professional chess games that took place during that time.

The team said: "This provides a precise and comparable measurement of individual performance for the same individual at different ages over long periods of time."
In the study, the team wrote: "Over the past 125 years, performance has improved, especially for individuals less than 20 years of age."
Research also pointed out humans are getting collectively smarter, as there has been an increase in chess playing performance since the 1890s.
Earlier this year a study found our drive and ambition peaks at the age of 33.

This is the point we are most motivated and determined to achieve their goals – from career progression to being physically fit and maintaining a healthy lifestyle.
The drive we have at this age is down in part to being more confident, having higher levels of energy and adopting a positive outlook on life.
While determination to succeed may be at its peak during our early to mid-thirties, motivation is still a struggle for most adults overall, with half admitting it is "a battle".
