Cloning, the mind, and immortality.

Something which has been running around in my head of late.

Firstly, I asked myself, if I was given the choice of living indefinitely would I take it? Certainly I would.

In popular media immortality is presented as a double edged sword - the allure of everlasting life, versus the inability to end it when life becomes a pain. I would have to think more carefully about that; but if humanity is to develop a means to indefinite life, it will most likely be without that second clause. So yes, I would do it.

But how? What conceivable ways could a human retain life forever?

A number of possibilities present themselves. The first is simply medicine and lifestyle; in the last millenium - even in the last two hundred years, the expected human lifespan in developed countries has skyrocketed, mainly due to increased knowledge of health, wellbeing, and the ability to target diseases with increasingly complex medical ideas and technology. Some would say this is only a temporary solution - nothing can stop the mind from deteriorating, the body's organs from failing after so many years. But what about when science is able to synthetically replicate organs, or when nanotechnology is able to repair and replace broken neurons in the brain? Once the human body is fully understood (and there is no natural law to prevent this) such procedures will enable humans to far surpass their current lifespans.
