I'm short-sighted, and I've long noticed this when standing somewhat far away from a mirror. If I'm close enough that I can easily see my reflection, but not so close that I can see that it's definitely me, I get the illusion that I'm looking at somebody else, and then I see myself as the older person that others see rather than the younger man that I'm practised at seeing ;) Aging doesn't seem to be linear, so I have to say this was more alarming when I was 30 (expecting to see a 24 year old) than it is now I'm 39 (expecting to see a 33 year old). But ask me again when I'm 50.
