HAVE you ever wondered how old you look to other people?
This clever (but ego-destroying) new tool by Microsoft can figure that out for you. Using hi-tech detection software How Old analyses your face and takes a stab in the dark at your age.
The results are a mixed bag, ranging from the very flattering to the not-so-flattering.
There is only so much entertainment you can get out of a computer telling you that you look 20 years older than you do - so we decided to see how the best-known faces among the Irish in Britain fared.
Take a look below...
Some of the results were almost spot on...
Una Foden, 34 (actual age: 33)
Graham Norton, 54 (actual age: 52)
Christine Bleakley, 37 (actual age: 36)
Others were not too far out...
Chris O'Down and Dawn O'Porter, 46 and 31 (actual ages: 35 and 36)
Dara Ó Briain, 48 (actual age: 43)
Some of the results were downright flattering!
Eamonn Holmes, 33 (actual age:55)
Dan Mulhall, 38 (actual age: 60)
But, of course, there were a few that were a little bit harsh...
Niall Horan, 33 (actual age: 21)
Mrs Brown, 66 (actual age: 59)
Perhaps none more so than poor Louis Walsh...
Louis Walsh, 88 (actual age: 62)
