Thanks, Jason,
i did not think in marvels of (reductionist) physics when contemplating
mentality - my mistake, but that's where I live in.

I don't 'make' copies and have no idea "how many" of "how many" details will

destroy the identity, when there are more and less qualifying aspects. You
may recognise a unit from just a few characteristics while eliminating a
lot  still
let you stay with the same one.
When it comes to a clash between common sense and theoretical physics, I am
with the former one.
