Consistency

 Consistency is a lot to ask of anyone, and maybe is not even necessarily always a good thing - the ability to discard old unsatisfactory patterns and beliefs and adopt new ones may be very healthy rather than being stuck like a robot in the same mode of being forever. However, one area we might reasonably expect relative consistency from someone is in the shape of their ears. These features should be pretty stable and consistent, even if our body may sag a little in places as it ages.

Here above is Joe Biden, and down below we are reliably informed is also Joe Biden, though it seems with a different set of ears - or at least a different right ear. Below him is again Joe Biden, sporting those same ears, but underneath that Joe Biden we see what seems to be the first pair of ears above make another appearance.

Earlobes are either ‘attached’ in which case they are attached to the side of the head, or ‘detached’ where they are only connected to the ear itself. Mr Biden appears to inhabit a very unusual spectrum where sometimes his earlobes are attached and sometimes they are detached. It appears from a little looking that images of the younger Biden all show detached lobes, while in more recent years it seems to have become less predictable what form they will take. 

Is this some special adaptive skill Mr Biden has developed over the course of his political career, or is there some other key to the mystery? Could it have something to do with his dementia? 

You might also notice that when Joe’s earlobes become more attached to his head, the gap between his mouth and nose extends, whilst his nose itself shrinks. More anatomical mysteries. His voice and manner of speaking also change quite significantly once these changes have occurred.
