Note that there's a difference between predicting your age and estimating how old somebody looks (i.e. you could look older for your age).
The same thing on photos of others I tried: a 22-year old man was estimated to be 49, a fifty-year-old woman--who is generally considered to look young for her age--to be 69. Those are ages that no one would ever guess based on looks.
So I'd say the algorithm needs a little more work.
