Here we see two pictures of John Lennon, one taken in 1963 when he was 23, the other from 1974 when he was 34:

There is virtually no difference between these photographs, taken 11 years apart. Notice how perfectly all of the features fall on top of each other, the teeth, the eyes position, the overall head shape: even his Adam's apple perfectly matches.

The photos of Paul we will be using are taken from more accurate angles, and yet they do not match anywhere near this well after late 1966..

A person's skull stops growing somewhere between the ages of 17 and 21. After this point, barring disfigurement, the size and shape of the skull is set for life. It neither gets longer nor wider, and the position of skull based features such as the eyes, nose, chin and ears stay absolutely fixed. All that changes is the distribution of fat in the cheeks and the wrinkles in the skin.

Here we see two photos of Jane Asher, Paul's girlfriend throughout most of the 60's, taken probably about 30 years apart (before you view this one, be aware that she had the bridge of her nose straightened between the photos, so this change is NOT a product of the camera angle.)

In this comparison as well, aside from the extreme chubbiness and a slight change in the camera angle, there is virtually no change. The key thing to note is that the indentation of the eyes sockets, the outline of the skull, the spacing between the ears and the base of the chin are all copletely unchanged. The nose would be as well if not for her corrective surgery. To the naked eye these photos do not look like they will match, but the comparison doesn't lie. Excess fat can change the character of someones face a great deal, but it cannot change the underlying features which are based in the skull. After the very early 20's these features are set for life, as you can easily see from these comparisons.
