A philosophy paper that I was reading yesterday makes this statement:
"With the exception of some brain cells, the cells in our bodies are
replaced with new cells several times in our lives."  Unfortunately no
reference is given.

I've heard a stronger version of this that says that over a period of
ten (?) years of so, the normal process of cell repair causes every atom
in our bodies to be replaced. I don't have the foggiest idea where I read
it, though, and I haven't been able to find it anywhere.

Are either or both of these statements true?  I'm writing a paper for 
a philosophy of mind class, and it would help me greatly if I could
find a reliable reference to either, especially the latter.
