Let that sink in – over half a century of marriage. It’s by no means a small feat.
According to her dad, the secret is “It’s not about love”.
“He said ‘What it comes down to is I made a commitment. We took that commitment really seriously so you understand that just because somebody annoys you or you have days of going ‘I can’t believe I’m with this person’ that you ride it out’,” Sparrow recounted on the latest episode of The Well podcast.

“‘Overall there are going to be great days and bad days, days where they irritate the hell out of you and others where it’s terrific. I don’t know, it’s as simple as going I’m seeing this through’.”
But what happens when your marriage doesn’t work out like that? Or when you realise the person you married isn’t someone you want to spend the rest of your life with?
Both hosts know that feeling well and spoke about why both their first marriages were big mistakes.
“When I got married the first time it was so stupid. I married a really good mate and I married him because I thought, we were working together and then we would hang together travelling Australia working, which is a really dumb ass idea to get married,” said Bailey.
"And he's still a great mate of mine and we just looked at each other after 18 months and went 'That was dumb!'".
Sparrow reckons her first marriage "out-dumbs" that.
"I married my American boyfriend in Las Vegas! Don't talk to me about dumb!," she started.
"I was a travel writer at the time. So we got married secretly in Vegas and didn't tell people, and then I said 'Bye" and was going to come back to Australia so we could get the green card so we could live in the states together. And then I didn't see him for seven years or whatever."
