I had a theory once when I was about 12 that the universe really was built around me... in fact, it was built around everyone. That every time I nearly died, I mean, came really close like nearly hit by a car, or crash my bike into a tree head first... my consciousness jumped into a different dimension where I didn't die. And that everyone lives to at least 100, maybe more. Maybe forever. That every one of those "amazing man lives to 110" people... it just happens that we're in the dimension that sees them live to the full age. Demented thoughts really. I lived in a country town... I was bored.

When I came up with this theory I never thought to extend it to it's logical conclusion, that everyone is immortal.

Recently I read "Divided By Infinity", a short story by Robert Charles Wilson, published in "The Year's Best Science Fiction : Sixteenth Annual Collection" [1999]. This story has a very similar theme to the theory I described except that it does extend it beyond the 100 year limit I arbitrarily provided.

Recently Dave forwarded me a blog post in which the book "Time Slip" [1986] by Graham Dunstan Martin is discussed. Again, this story has a similar theme of immorality via dimension jumps.

I intend to track this book down and read it.
