Some of the greatest achievements from the Tokyo Olympics so far have come from athletes who are in their teens. Team GB's Sky Brown has won a bronze medal for skateboarding at the age of 13, and Team USA sprinter Erriyon Knighton breezed his way into the Men's 200m final at the age of 17.
All of the young blood at this year's Olympic Games has got people wondering what the minimum age requirement is for athletes to compete in the Olympics.
How old do you have to be to compete at the Olympics?
You may be surprised to hear that there isn't actually a minimum age requirement to enter the Olympics.
The Olympics website states: "There is no specific age limit for taking part in the Olympic Games. This depends on each International Sports Federation [ISF] and the rules it lays down for its sport."
Each sport has an ISF, which is in charge of arranging the qualifying events and determining if an athlete meets all of the requirements set out in the Olympic Charter.
