This is true only if you look at the integers as an ordered set and then only in the usual order. What proportion is even if you put them in the order:
putting n odd numbers between 2n-2 and 2n? As far as anyone knows, there is no way of ordering the universes and Stranger's point is well taken. Anyway, I'll take a flier and say the odds are 0. Suppose there is a universe out there just like ours except the gravitational constant differs in the 10th decimal. Maybe life would still be possible, maybe not. How could we know? I think the question is essentially meaningless.
