The Number of Different Lives

Just a thought that occurred to me, though it was interesting enough to share:

The human brain has about 100 billion neurons. Assume a nueron can either be on or off (probably not a great model, but close enough for the purposes of this idea). The brain can then be in one of 21011 different states. Assume further that the shortest experience has a duration of 1/10th of a second, and that humans live for no more than 120 years.

There are then 21011310 possible lives. It should actually be significantly less because one would assume you can't get from some particular states directly to other particular states.

That might seem like a huge number, but it's much smaller than the number of states that the universe can be in.

This is actually very obvious but it seemed interesting to me.
