Here are some facts about a couple of professional athletes.
The oldest athlete to play baseball on a professional basis was Satchell Paige, who played his final Major League Baseball (MLB) game in 1965 for the Kansas City Athletics at the age of 59.
His final professional game at any level, was for the Peninsula Pilots in the Carolina League in 1966, 16 days short of his 60th birthday.
Satchel Paige was one of the earliest black players of Major League Baseball - as opposed to the segregated leagues, in which he had been playing since the age of 20 - joining the Cleveland Indians in 1948 aged 42. Paving the way for integration, he was only the 7th black player in MLB and the first black pitcher. He is widely regarded as one of the hardest pitchers in history, and one of the best.
The oldest player to take part at all in a pro game was Ted Radcliffe, who in 1999 at the age of 96 threw one pitch for the Schaumberg Flyers playing in a Northern League game. Ted Radcliffe started his professional career in 1928 at the age of 26 and continued until on the playing side until the age of 52.
Paige's attitude to age - "Age is a question of mind over matter. If you don't mind, it don't matter".
