6 Reasons You May Live to Be 100

Here are some clues that MIGHT mean your chances are good...are you kidding me? who wants to live to be 100?  sounds painfully long

#1.)  You have a lot of old relatives.  There's a lot of evidence that longevity has a lot to do with genetics.  At least half of all people who live to be 100 also have a sibling, parent, or grandparent that reached 90-plus.

#2.)  You can walk fast over long distances.  One study found that the average person typically walks about two miles per hour . . . and for every two-tenths of a mile per hour faster than that, a person would have a 12% decrease in the risk of death.

#3.)  You have a lot of friends.  The more you interact with other people, the more likely you are to live a long time.  And lonely people tend to die earlier, and be less healthy in general. Sorry.

#4.)  You're a woman.  Out of roughly 80,000 Americans who are older than 100 today, 85% are women.  And women who bear children naturally beyond the age of 40 are FOUR TIMES more likely than other women to live to 100.

#5.)  You worry just enough to stay safe. New research says that SOME worry is actually good for you. It might cause stress, but people who worry -- as long as it's within reason -- actually live longer on average.

#6.)  You have a positive attitude. Lots of studies suggest that a positive outlook on life tends to give you more years. Obviously if you tend to stay happy, you experience less stress, and that can help you stay more healthy.
