Chamberlain was fit enough in his mid-forties to humble a young Los Angeles Lakers rookie called Magic Johnson in practice, and even in the 1980s, he flirted with making a comeback in the NBA. In the 1980-81 NBA season, coach Larry Brown recalled that the 45-year old Chamberlain had received an offer by the Cleveland Cavaliers. When Chamberlain was 50, the New Jersey Nets had the same idea, and Chamberlain declined again. Chamberlain however participated in several marathons instead. He would stay an epitome of physical fitness for years to come, until his health rapidly worsened in 1999.
