MICROSOFT HAS CREATED a new website which aims to guess your age.

How Old Do I Look, which uses algorithms to scan human faces in uploaded photos, has swept the world since its release this week and, while it is relatively accurate in some circumstances, many people have been complaining on social media that it is way off.

We’ve decided to put it to the test with some of Ireland’s best-known athletes.

Paul O’Connell (actual age: 35)

Rory McIlroy (actual age: 25)

Katie Taylor (actual age: 28)

Conor McGregor (actual age: 26)

Mick O’Dwyer (actual age: 78)

AP McCoy (actual age: 40)

The Kilkenny senior hurling team

Roy Keane (actual age: 43)

And, for the week that’s in it…

Floyd Mayweather and Manny Pacquiao(actual ages: 38 and 36)

It’s pretty clear that it still needs a bit of work then. Have a go yourself on How-Old.net.
