A website that looks at pictures and sets the age "How old are you?"

There seems to be a site that looks at the picture "How old are you?" To age.

It is surprisingly difficult to fit the actual age closely, there is addiction that keeps getting nervous.

Details are from the following.
How old are you? Pic rating - pic age guessing, how old do I look. Real age calculator

Easy operation. Just choose the number that you think is "this" by looking at the picture.


Then the answer is displayed on the picture on the right side of the screen and the average of the age anticipated by other people is displayed below the picture. The following problem is also displayed on the left side of the screen.


It is made me realize that the age of a person is not understood by just a face.
