Also, I just now noticed that you -did not answer the question-, and that it's a critically important question. How do you define the term 'person', as questioned above? That definition has nothing whatsoever to do with anthopic properties or inference.

I don't see that as being a valid property. Your existence purely in isolation does not allow you to infer anything. Did you mean something more along the lines of "'my' existence in addition to other information X allows me to infer things..." instead? If so, it would be helpful if you clarified exactly which other information is involved.

It does not as you don't obtain any world properties that 'your' existence should reflect with such a definition.
