22, 45, forever

When my parents wed at 28, it was on the understanding that my father was only agreeing to stay around until he was 50.

My mother says this was because he'd already worked a thousand jobs (across this country and overseas) and couldn't imagine committing to something forever.

At 73, they're still together. It's no exaggeration to say they are devoted to each other.

When Mum reminds him of the expiry date on their marriage, Dad jokes, "You learnt to cook too well."
