The retired dentist, who took up exercise in his 80s, clocked in at 55.48 seconds, easily toppling Orville Rogers' 57.88 set in 2013. According to the Silver Grey Sports Club, Eugster set a British record for 60 meters the day before.
The Telegraph has called Eugster "the world's fittest pensioner." He plays all kinds of sports but took up competitive track in 2013.
The newspaper wrote that he eats fresh fruit in the morning and gulps a protein drink after workouts.
On his website, Eugster offered these general tips for winning at life: "Successful agingrequires work, diet and exercise. The huge mental and physical potential of the aged remains unexplored. Bodies can now be rebuilt at any age and a new life started."
Who's gonna argue with this guy?
