Re: Will cloning bring humans a step closer to immortality?

Many people are confused about cloning and think it is a new copy 
of themselves. However in fact it is a new individual with the same
genetic makeup. If you had an identical twin, that would essentially be
the same as having a clone.

Your clone would NOT have your memories or ideas. It would start out as
an infant and grow up normally. It would not have your age, it would start
over.

You are correct in assuming that you could harvest organs from a clone and
not have to worry about rejection. However this would not assure immortality,
only a supply of organs in case you have a heart or kidney or liver 
problem. But it is not as if you can change all the parts of your body
(your muscles, bones, brain, nerves, intestines and lots
of other parts are not replaceable and would still be old.) This of course
doesn't deal with the ethical problems (would you kill your identical twin
to obtain their heart for a heart transplant?)
