Michael O'Keeffe, Vancouver, at ages 32 and 68
WHAT HE KNOWS NOW THAT HE WISHES HE HAD KNOWN THEN:
"I had 3 wives between 1965 and 2000. The only advice I would give to my younger self is this - If at first you don't succeed, give up and start running. Cos it ain't gonna get any better. Marriage is a big waste of time, effort and money."
