Here’s a bit of fun. Microsoft has this brand new free & fun page called How Old, in which you stick a photo and the bot will then try to estimate your age from the evidence. For what it’s worth, to try it out I just stuck a shot of yours truly plus a friend (who will remain nameless) into it. The result was the bot assuming I’m two years younger than my true age and my friend is estimated at six years older than his reality.
To be honest, both those results look spot on to me. Smart machine. Go try it
