A simple test to predict longevity

A recent study shows that being able to sit on the floor and stand up with little help of your hands is strongly correlated to longevity in old age. Based on a 10 years research of 2000 men and women with 50 to 80 years old, those needing extra assistance, such as getting up on their knees or using two hands, are up to six times more likely to die prematurely.
“It is well known that aerobic fitness is strongly related to survival, but our study also shows that maintaining high levels of body flexibility, muscle strength, power-to-body weight ratio and co-ordination are not only good for performing daily activities but have a favorable influence on life expectancy”
So, here is a simple way of checking how healthy you are: just sit down, get up, and keep in good shape and balance to reach 100 years!

Society effects on Longevity - The Roseto Effect

An article from New York Times magazine brings up some new aspect of longevity: your community.


In the island of Ikaria, the mediterranean diet and active lifestyle are a big factor for old age and health, but places with very high longevity (Ikaria in Greece, Sardinia in Italy, Okinawa in Japan, 7th Day Adventists in California) have another secret: a strong and healthy social structure.

If you pay careful attention to the way Ikarians have lived their lives, it appears that a dozen subtly powerful, mutually enhancing and pervasive factors are at work. It’s easy to get enough rest if no one else wakes up early and the village goes dead during afternoon naptime.  
This phenomenon has a name: The Roseto Effect describes the uncommon health and longevity of citizens from Roseto, Pennsylvania (USA) in the 50s and how these differences disappeared as Roseto became more "Americanized" in the 1960s. The studies point that erosion of traditionally cohesive family and community relationships increased the mortality rate.

Seems that we should cultivate strong community ties, together with a healthy life style, to become healthy centenarians, and a healthy society make it easier for its members to have better health and longevity.

Hat tip for BoingBoing for bringing it up!

Why We Age

Hank (from SciShow) do a quick review on the current scientific knowledge on aging and what can we do about it:


While there's been interesting advances in genetics that promise to increasing our lifespan by 33%, it will be a long time until these are available for humans. Till there, you can review your genealogical tree for long life-span relatives (accounts for up to 30% of your chances of living till 85), and keep a healthy life-style (diet, regular exercise and avoid smoking and alcohol).

What are the odds of dying from...


An amazing infographic on the odds of dying from different injuries and accidents from US NSC Injury Facts Book (2011):

A bit of background: The U.S. National Safety Council publishes statistics of death and injuries since 1920. Their latest publication is the Injury Facts® Book, 2011 Edition.

Responding to frequent inquiries asking questions such as, "What are the odds of being killed by lightning?" or "What are the chances of dying in a plane crash?" the Injury Facts® 2011 edition includes a comprehensive table of the odds of dying from a variety of causes.


It's interesting to note that the most prevalent deaths are health related (Heart disease, Cancer, Stroke) so to live longer a healthy life-style is a good start!

The Fat Trap (NY Times article)


The NY Times published an article about weight loss: The Fat Trap. Science shows that loosing weight is harder after you're over weight.

... to lose weight and keep it off, a person must eat fewer calories and exercise far more than a person who maintains the same weight naturally. (...) Years later they are paying attention to every calorie, spending an hour a day on exercise. They never don’t think about their weight.

As weight is one of the high correlated factors of life expectancy, it's interesting to know that we should strive to keep our weight down, and for the ones trying to loose weight (like me) it will be double hard to loose and maintain the lower weight.
