I wouldn't be surprised if Federer retires within the next couple of years, then comes out of retirement after a 2 year absence and wins his umpteenth slam at the ripe old age of 40.

But when was the last time someone won a slam at 85, as Federer just did.

You need a litle update because Wawrinka has won 2 Slams at the age of 30+
