6 Foods to Keep You Young
Olive Oil
Four decades ago, researchers from the Seven Countries Study concluded that the monounsaturated fats in olive oil were largely responsible for the low rates of heart disease and cancer on the Greek island of Crete. Now we know that olive oil also contains polyphenols, powerful antioxidants that may help prevent age-related diseases.
Yogurt
In the 1970s, Soviet Georgia was rumored to have more centenarians per capita than any other country. Reports at the time claimed that the secret of their long lives was yogurt, a food ubiquitous in their diets. While the age-defying powers of yogurt never have been proved directly, yogurt is rich in calcium, which helps stave off osteoporosis and contains 'good bacteria' that help maintain gut health and diminish the incidence of age-related intestinal illness.
Fish
Thirty years ago, researchers began to study why the native Inuits of Alaska were remarkably free of heart disease. The reason, scientists now think, is the extraordinary amount of fish they consume. Fish is an abundant source of omega-3 fats, which help prevent cholesterol buildup in arteries and protect against abnormal heart rhythms.
Chocolate
The Kuna people of the San Blas islands, off the coast of Panama, have a rate of heart disease that is nine times less than that of mainland Panamanians. The reason? The Kuna drink plenty of a beverage made with generous proportions of cocoa, which is unusually rich in flavanols that help preserve the healthy function of blood vessels. Maintaining youthful blood vessels lowers risk of high blood pressure, type 2 diabetes, kidney disease and dementia.
Nuts
Studies of Seventh-Day Adventists(a religious denomination that emphasizes healthy living and a vegetarian diet) show that those who eat nuts gain, on average, an extra two and a half years. Nuts are rich sources of unsaturated fats, so they offer benefits similar to those associated with olive oil. They’re also concentrated sources of vitamins, minerals and other photochemical, including antioxidants.
Blueberries
In a landmark study published in 1999, researchers at Tufts University’s Jean Mayer Human Nutrition Research Center on Aging fed rats blueberry extract for a period of time that in 'rat lives' is equivalent to 10 human years. These rats outperformed rats fed regular chow on tests of balance and coordination when they reached old age. Compounds in blueberries (and other berries) mitigate inflammation and oxidative damage, which are associated with age-related deficits in memory and motor function.
Cage of Death - Australia
Pictured: The theme park's 'cage of death' that drops tourists into a crocodile's lair
Without the cage you wouldn't stand a chance swimming with a massive saltwater crocodile.
But for brave punters who still want to get cosy with a feisty croc, a new Australian tourist attraction is offering the chance for a close encounter in the safety of a clear acrylic box dubbed the 'cage of death'.
Just 4cm of acrylic, a pair of goggles and a swimsuit, will separate thrill-seekers from the jaws of Choppa, a saltwater crocodile.

The cage has no bars, unlike cages used in shark dives, which prevents the reptiles from gripping on but deep teeth scratches are visible on the sides, deterring some hesitant participants.
Top End tourists climb into the clear box before being lowered into Choppa's lair.
They then spend 15 minutes inside the 9ft high cage and watch Choppa, who lost both front feet while fighting other crocodiles, trying to take a bite out of them.

The attraction at Crocosaurus Cove in the heart of the city of Darwin in the Northern Territory has been given high marks by adrenaline-junkies.
'This is it!' said self-confessed thrill-seeker Mark Clayton from Darwin after spending 20 minutes face-to-face with the crocodiles.
'I dive with sharks, large rays, moray eels ... but it's not this close. It's exhilarating to get that close to a crocodile of that size.'
Face-to-face: The experience is made even more thrilling for tourists because the cage has no bars
Saltwater crocodiles, known locally as "salties," are the largest crocodile species, with the males growing up to 19.6ft long and weighing up to 2,204lbs.
They are found in across Southeast Asia but the highest numbers are found in northern Australia .
Michael Scott, who opened the attraction in July, said there was plenty of demand for the £35 thrill.
'In the Northern Territory , the saltwater crocodile is an icon and is part of our life. They are always in the news, either in someone's swimming pool or killing someone's favourite horse,' Mr Scott said.
Hunting for food: Up to two people are allowed in the cage at the one time
The most famous crocodile to be housed at the park is Burt, who starred as the beast that nearly ate Linda Koslowski's character in Crocodile Dundee .
Although saltwater crocodiles are dangerous, fatal attacks on humans are rare in Australia with only one or two reported a year.
Warning signs are displayed at rivers, lake and beaches in areas inhabited by crocodiles.
Dicing with danger: Swimming face-to-face with a massive saltwater crocodile might not be everyone's idea of fun but thrill-seekers are snapping up Australia 's newest tourist attraction
The most recent fatality was reported last month in Queensland when the suspected remains of a British man were found inside a crocodile.
Arthur Booker, 62, was last seen checking crab pots on a crocodile-infested river in the state's north.
