To know your birthday requires log(n) bits, which goes to infinity as n goes to infinity.

Fortunately, 30 July 1939 doesn't got to infinity.  It stays the same.

Without an ever expanding memory, you are limited to experiencing at most M^2 states, where M is your memory capacity in bits.  If M is finite, then infinite years don't matter, you will begin to revisit previous states.

That 2^M.

By that kind of reasoning the universe will revisit previous states and there's no meaning to "immortality".  But there's still obvious meaning to living a 10,000yrs vs 100yrs.
