Lifetime sports are those which are enjoyed by the young and the old. Sports which can be enjoyed at various intensity levels: golf and tennis are excellent examples. Soccer would not be considered a lifetime sport because it involves so much running. American football would not be considered a lifetime sport because it involves both running and tackling. The "soft" martial arts such as Tai Chi and KungFu are considered lifetime sports while the "hard" martial arts such as taekwondo, judo and karate are not because they involve strikes and grappling.
