HEALTHY LIVING# NEWS

(The following is a part of Msn.news regarding living longer-very interesting regarding the telomeres: WORLD HEALTHDAY-4/7/2012. http://www.msn.com/)
How long are your telomeres?
(The following is very interesting information-New World)

What it may mean: Many people who live to 100 have a hyperactive version of an enzyme that rebuilds telomeres.
"What-o-meres?" you ask. Telomeres are protective DNA sequences at the ends of chromosomes that gradually shorten as cells divide. (Pioneering telomere researcher Elizabeth Blackburn of the University of California-San Francisco compares them to shoelace caps.) Eventually the telomeres become so short that cells stop dividing, a condition called senescence, creating the effects we recognize as aging in related tissue.


Scientists are still unraveling the key role telomeres seem to play in aging, cancer, and other biological processes, but this much is clear: The longer your telomeres, the more time you're apt to have left. A 2010 Italian study reported that cancer-free people with shorter telomeres were more likely to develop cancer within ten years than those with longer telomeres, for example.
Some studies show that removing chronic stress, not smoking, and eating a diet rich in omega-3 fatty acids can improve telomere length. Those centenarians with hyperactive telomere-making apparatus can probably thank their genes, though.
New blood tests are now being marketed directly to consumers, purporting to predict longevity based on telomere length. But critics caution that there aren't standards for measuring telomere length and that there can be such variability in telomeres that it's hard to predict much of anything from a sample.
