Forget dreams of eternal life!

It is the holy grail for scientists, to create a future where humans can achieve everlasting life. But it will only ever be science fiction, a study suggests, as it is impossible to stop the march of time. Researchers who looked at aging have concluded there is'no way out' of death even with a breakthrough in drugs or treatment. The problem as we get older is that some cells become sluggish, so our bodies slow down and organs do not work properly, while other cells speed up and cause cancer. We could slow down cancer cells to stop them in their tracks, but this would probably worsen the effects of aging.
