For Mr. Kluytmans (and I may have more to say, too):

In biology things do not simply wear out. That is false as an 
explanation of aging and equally false when applied to biological
parts. If they wear out, it will be because the energy and materials
cost of making new ones is less than the cost of maintaining old

As for diamond materials, there is a problem with what you say
here too. Right now biological systems have no reason to evolve
any means to consume diamonds. They are too rare to give much 
benefit if consumed. (Remember that they are carbon, a basic
material of living things). If we start making and using lots 
of nanotech devices which use diamond, that situation will change.
So many good sources of carbon lying about! If we can make diamond
without expending lots of energy to do so (high pressure and high
temperature) then biological systems will evolve able to destroy
it --- literally eating it up --- with similar low energies.

More as I read on.

             Best wishes and long long life for all,

                 Thomas Donaldson
