Someone irl mentioned recently that you only ever see photographs of yourself, or videos, or a reflection in a mirror, not actually yourself.
So say a little bit in the future you travelled back in time and saw yourself walking around in the streets, just as you would today.
Would you recognise yourself?
Perhaps you would remember being on a particular street on a certain day wearing certain clothes, so your future self would probably be able to locate your current self without too much trouble.
But your current self would not know that your future self was wandering around in this time, wouldn't know what you were (going to) wear, nor where you would be.
Assuming that you hadn't changed beyond recognition, would you recognise your future self?
