Scientists have shown that feeding a simple polyamine called spermidine to worms, fruit flies and yeast significantly prolongs their lifespan. In addition, adding spermidine to the diet of mice decreased molecular markers of ageing, and when human immune cells were cultured in a medium containing spermidine, they also lived for longer.Spermidine - a simple linear molecule found in large quantities in human sperm and grapefruit - is known to be necessary for cell growth and maturation, and as cells age their level of spermidine is know to fall. Now, Frank Madeo from the University of Graz in Austria and his colleagues have shown...

So what does the world's oldest man eat? The answer is not much, at least not too much. Walter Breuning, who turned 113 on Monday, eats just two meals a day and has done so for the past 35 years. "I think you should push back from the table when you're still hungry," Breuning said. At 5 foot 8, ("I shrunk a little," he admitted) and 125 pounds, Breuning limits himself to a big breakfast and lunch every day and no supper. "I have weighed the same for about 35 years," Breuning said. "Well, that's the way it should be."...

Reliapundit alerts us to breaking news: Gertrude Baines, who lived to be the world's oldest person on a steady diet of crispy bacon, fried chicken and ice cream, died Friday at a nursing home. She was 115. Baines, who remarked last year that she enjoyed life so much she wouldn't mind living another 100 years, died in her sleep, said Emma Camanag, administrator at Western Convalescent Hospital. The centenarian likely suffered a heart attack, said her longtime physician, Dr. Charles Witt. An autopsy was scheduled to determine the cause of death. ...Staff at Baines' nursing home described her as a...

Is it really possible for anyone to live happily to 100? The good news is that your body was designed to be 100 - you just have to get out of the way. Getting out of the way means taking an honest look at the habits and lifestyle you are living with today. Most of us have developed habits that limit our true health potential. But don't let these bad habits of the past discourage you - it is never too late to make new choices. What you did in the past can be changed, and your body will respond...

The Centers for Disease Control and Prevention, often the harbinger of bad news about e. coli outbreaks and swine flu, recently had some good news: The life expectancy of Americans is higher than ever, at almost 78. Discussions about life expectancy often involve how it has improved over time. According to the National Center for Health Statistics, life expectancy for men in 1907 was 45.6 years; by 1957 it rose to 66.4; in 2007 it reached 75.5. Unlike the most recent increase in life expectancy (which was attributable largely to a decline in half of the leading causes of death...

U.S. life expectancy has risen to a new high, now standing at nearly 78 years, the government reported Wednesday. The increase is due mainly to falling death rates in almost all the leading causes of death. The average life expectancy for babies born in 2007 is nearly three months greater than for children born in 2006. The new U.S. data is a preliminary report based on about 90 percent of the death certificates collected in 2007. It comes from the National Center for Health Statistics, part of the Centers for Disease Control and Prevention. Life expectancy is the period a...

Could a pill one day slow ageing in humans?Punchstock Rapamycin, a drug commonly used in humans to prevent transplanted organs from being rejected, has been found to extend the lives of mice by up to 14% — even when given to the mice late in life. In flies and worms, drug treatments have been shown to prolong lifespan, but until now, the only robust way to extend life in mammals has been to heavily restrict diet. The researchers caution, however, that using this drug to extend the lifespan of humans might be problematic because it suppresses the immune system —...

A study published Wednesday found that rapamycin, a drug used in organ transplants, increased the life span of mice by 9% to 14%, the first definitive case in which a chemical has been shown to extend the life span of normal mammals. Anti-aging researchers also expect a second study, to be released this week, will show that sharply cutting the calorie intake of monkeys extends their lives substantially. The experiment is said to be the first technique shown to retard aging in primates ... The Wisconsin study, which began in 1989 with 30 monkeys and added 46 more in 1994,...

Being overweight won’t kill you — it may even help you live longer. That’s the latest from a study that analyzed data on 11,326 Canadian adults, ages 25 and older, who were followed over a 12-year period. The report, published online last week in the journal Obesity, found that overall, people who were overweight but not obese — defined as a body mass index of 25 to 29.9 — were actually less likely to die than people of normal weight, defined as a B.M.I. of 18.5 to 24.9. By contrast, people who were underweight, with a B.M.I. under 18.5, were...

People die, but one part of them, at least in principle, is immortal. In the germline cells that produce eggs or sperm, biological time stands still. This is why babies are all born with the same age, the clock set to zero, regardless of the age of their parents. A little piece of the germline’s immortality, it now seems, can be acquired by the ordinary cells of the body, and used to give the organism extra longevity. This is the conclusion of a research group at the Massachusetts General Hospital led by Sean P. Curran and Gary Ruvkun. Their studies...

The oldest survivor of the First World War, Henry Allingham, is celebrating his 113th birthday with a party organised by the Royal Navy. The veteran soldier also holds the record as the last survivor of the Battle of Jutland, the last surviving member of the Royal Naval Air Service and the last surviving founding member of the Royal Air Force.

A man's chances of dying early are cut by a fifth if their bride is between 15 and 17 years their junior. The risk of premature death is reduced by 11 per cent if they marry a woman seven to nine years younger. The study at Germany's Max Planck Institute also found that men marrying older women are more likely to die early. The results suggest that women do not experience the same benefits of marrying a toy boy or a sugar daddy. Wives with husbands older or younger by between seven and nine years increase their chances of dying...

Want to live to a ripe old age? By far the most important factor in life expectancy is wealth; richer people tend to eat healthfully and smoke and drink less. They also have access to the best health care. Affluent countries also tend to have low rates of violent crime and civil unrest. The following countries have the highest average life expectancies in the world. In case you're wondering, the United States, with an average life expectancy of 77.85, ranks 48th. Get started now and see the list of countries with the highest life expectancy. 1. Andorra: 83.51 Years Located...

A woman in Kazakhstan who officials said was the oldest in the world at 130 has died after slipping on the bathroom floor of a new flat she was awarded by the state because of her great age. Sakhan Dosova - a mother of ten - said she never visited a doctor nor ate sweets. She was addicted to cottage cheese and put her longevity down to her sense of humour. She received worldwide publicity in March after her alleged age came to light in a census in the former Soviet republic. Demographers were astonished to find that she was...

Too bad Ponce de Leon didn't live in 21st century New York City. He may not have found the Fountain of Youth, but he would have at least gotten a book deal. It seems that every time a Baby Boomer finds a gray hair, another tome is written promising to teach people how to stave off the effects of aging. This year, dozens of self-help titles are set to hit the shelves, all offering tips to extending youth.

SHELBYVILLE, Ind. (Nov. 27) — Edna Parker, who became the world’s oldest person more than a year ago, has died at age 115. UCLA gerontologist Dr. Stephen Coles said Parker’s great-nephew notified him that Parker died Wednesday at a nursing home in Shelbyville. She was 115 years, 220 days old, said Robert Young, a senior consultant for gerontology for Guinness World Records.

A woman celebrating her 105th birthday says that celibacy and staying single has been the key to her long life. Clara Meadmore, a retired secretary, who still has her own hair, teeth, and sharp wit, never had time for a family and lived alone until going into care. She said: "I've always had lots of platonic friendships with men but never felt the need to go further than that or marry." "When I was a girl you only had sex with your husband and I never married. I grew up in an era where little girls were to be seen...
