can you prove your identity?

[Michael Joseph]

I can see your first point, it is all relative and subject to change at any given moment.

My direction was more towards description of body rather then name though.

Exactly. Look at a Stream. It looks the same most every day. But is it? Each second new Hydrogen and Oxygen elements are coming and going. So in effect the Stream is NEVER the same. So tell me what about Man is ever the same so that we can gain a purchase on Identity? Nothing!
