He's never drunk alcohol and never smoked a cigarette.
It's little wonder then that Sek Kwon, known to friends as "Ye Ye," celebrated his century on Wednesday with a party laid on by the Richmond Kinsmen Adult Day Centre on Bowling Green Road, at Minoru Park.
Ye Ye - born 100 years ago in Ningpo, China near Shanghai - marked the occasion with a lunch with family, friends and fellow Kinsmen clients, karaoke, a toast, a telegram from the Queen and, of course, birthday cake.
Through his father's three marriages, Ye Ye boasts a total of 10 siblings.
He came to Canada in 1976, following some of his seven children, who had immigrated already.
Two of them, Hilary Hui and Alphonsus Hui, are family physicians.
Hilary, who practices in Richmond, said his father is still very active for a centenariun even after suffering a stroke.
"He goes to Richmond Centre every morning for exercise class and he played ping pong every day before his stroke," said Hilary.
