Scientists working on 'eternal youth'

Organs in the body could be revived using drugs which would dramatically improve life expectancy, according to new research.

Scientists from the Dana-Farber Cancer Institute in Boston reversed tissue degeneration in mice by switching on a certain enzyme which prevents molecular aging.

The drugs, which are also being developed for human use, would keep individuals looking young, healthy and alert.

Lead researcher Dr Ronald DePinho said: "This unprecedented reversal of age-related decline in the central nervous system and other organs vital to adult mammalian health justifies exploration of telomere rejuvenation strategies for age-associated diseases."

Meanwhile, a rise in life expectancy, which could increase the number of older people wanting to find a care home, is sparking fears among pension companies.

Women currently aged 65 will live for a further 0.8 years, it is projected, until the average age of 90, whereas men of the same age will now live 0.4 extra years until 87.5.
