Finding a way to thwart death and live forever is the stuff of movies and legends -- how many characters have gone in search of the fountain of youth? That's all just fiction and fun, of course, but in real life there are real things you can do to help not only get the most years out of your life as possible but also the most quality years out of your life. A good start to a solid fitness plan is implementing healthy (i.e. life-extending) habits. So try these on for size:

• Get enough sleep, but not too much! Studies show that people who sleep too much (generally 8+ hours per night) have shorter life expectancies, but then again so do those who don't get enough sleep (less than 6 hours). It seems there's a magical number of just enough sleep, which for most people lands somewhere between 6 and 8 hours.

Researchers have found a link between education and life expectancy. Life expectancy in the US has been on the rise in recent decades, but the numbers are disproportionate. On average, those who continued education beyond high school have a life expectancy of 82. Those with 12 or less years of schooling have an average life expectancy of 75.

So what do books have to do with life span? Nothing really. Researchers attribute the difference to lifestyle. People with less education are more likely to have a lower income which can lead to subsequent health-related issues such as poor housing, crime, or lack of medical insurance. In addition, researchers feel tobacco usage may account for the discrepancy in life expectancy.

The good news is that a recent study found that patients with obesity and those who smoke actually cost less to treat over their lifetime than people who are thin and healthy.

The bad news? They cost less because they don't live as long.

It seems like common sense -- people who live longer have higher health care costs. But researchers were surprised to find out that people with obesity and those who smoke actually cost less in the long run than those who are fit. The research pokes holes in the alarmist theory that the obesity epidemic will cost billions as the obese seek help for their health issues.

It's an interesting study. What do you think?

In Medieval times, peasants lives relatively short lives compared to us -- elderly people were those who lived into their 40s, 50s and 60s. So the news that the Medieval diet was much healthier than ours should come as a shock, shouldn't it? Well, not really. Truth is, the Medieval people probably would have lived longer than most of us if they'd had our access to modern medicine and farming technologies.

Here's the thing: Medieval people ate much better than us. According to the BBC, they typically ate 8 oz of protein, a variety of fresh, organic vegetables and two loaves of whole wheat bread per day. Nothing was processed, and nothing was refined. Any sugar they got was typically from the fruits they grew. And they didn't go to the gym, but couple that with a day of physical labour and you've worked off those calories easily. They were fitter, and the reason they lived shorted lives than us was typically due to illness, starvation, pestilence and so forth.

Doesn't it seem odd that we have all this technology and yet we're going backwards in terms of life expectancy? It seems about time we started going back to basics. What do you think?

Researchers have discovered a fountain of youth, in a manner of speaking, for the fruit fly. At first you're probably thinking why on earth would we want longer living flies? The good news is that the researchers were able to extend the lifespan of fruit flies by modifying only one genetic protein, which means inhibiting the aging process in humans may be much simpler than previously thought.

Fruit flies with the modified gene saw 1/3 longer lifespans with no apparent side-effects (although measuring side-effects in a fruit fly can't be easy or very accurate), so if the same were true for humans we could all theoretically live to around the 110-120 yr old range regularly.

Cool or scary? A little of both, I think.

Recent numbers from the Australian Bureau of Statistics shows two very different bits of news: on one hand certain parts of the Australian population are among the longest living in the world, while other populations are among the shortest.

The nations capital, Canberra, boasts the longest life spans -- with women living an average of 84 years and men 79.9 years. But the indigenous Australians don't fair so well, with the average dropping about 17 years -- only 64.8 years on average for woman and 59.4 years for men. Why the dramatic gap? Poverty, substance abuse, and limited access to healthcare are the suspected culprits. Fortunately, these groups make up a very small percentage of the entire population of Australia.

Only 3 places in the world beat Australia's over-all life expectancy averages for men and women: Iceland, Japan, and Hong Kong.

I wish I could see where the U.S. ranks on that list.
