Coma patients are actually alive, though, and have been known to come back.

If you believe that dead people have come back, you're religious.

...this might be controversial, but I'll argue that thinking you'll live again if you get chronically frozen requires as much faith as believing you'll live again in an afterlife.

There's not much evidence for either, so you're left squinting heavily at vague suggestive outlines, making your bets, then hoping and trusting it works out.

The difference is what you put that faith in, and why.
