Things we do for ourselves die with us; what we do for others lives on and on
Drink Wine, Live Longer!
Red wine may be much more potent than was thought in extending human lifespan, researchers say in a new report that is likely to give impetus to the rapidly growing search for longevity drugs.
The study is based on dosing mice with resveratrol, an ingredient of some red wines. Some scientists are already taking resveratrol in capsule form, but others believe it is far too early to take the drug, especially using wine as its source, until there is better data on its safety and effectiveness.
The report is part of a new wave of interest in drugs that may enhance longevity. On Monday, Sirtris, a startup founded in 2004 to develop drugs with the same effects as resveratrol, completed its sale to GlaxoSmithKline for $720 million.
Sirtris is seeking to develop drugs that activate protein agents known in people as sirtuins.
"The upside is so huge that if we are right, the company that dominates the sirtuin space could dominate the pharmaceutical industry and change medicine," Dr. David Sinclair of the Harvard Medical School, a co-founder of the company, said Tuesday.
Serious scientists have long derided the idea of life-extending elixirs, but the door has now been opened to drugs that exploit an ancient biological survival mechanism, that of switching the body's resources from fertility to tissue maintenance. The improved tissue maintenance seems to extend life by cutting down on the degenerative diseases of aging.
The reflex can be prompted by a faminelike diet, known as caloric restriction, which extends the life of laboratory rodents by up to 30 percent but is far too hard for most people to keep to and in any case has not been proven to work in humans.
Research started nearly 20 years ago by Dr. Leonard Guarente of the Massachusetts Institute of Technology showed recently that the famine-induced switch to tissue preservation might be triggered by activating the body's sirtuins. Sinclair, a former student of Guarente, then found in 2003 that sirtuins could be activated by some natural compounds, including resveratrol, previously known as just an ingredient of certain red wines.

Now isn't that something! To be able to turn your body from fertility to maintenance mode all by drinking wine.
Cheers!
