Basil Smith makes the round trip of 80 miles from Carmarthenshire to Swansea twice a week to play tennis.
At 92 years old, he says the key to his success is by staying, "Young at heart, young in mind."
Basil says that, "Vital health is good, enjoy yourself but don't abuse yourself."
And he should know - he says he starts, and ends, every day with half an hour of exercise as well as visiting Swansea Tennis Centre on Mondays and Thursdays.
