Will You Live to Be 100?

ORLANDO, Fla. (Ivanhoe Newswire) -- The average American lives to be 77.8 years old, but the number of those living past 100 is growing. Will you be a centenarian? Some lifestyle factors may help determine your fate.

Will you live to be 100? Here are some surprising ways to tell ... are you outgoing? Swedish researchers found those who are have a 50 percent less chance of developing dementia.

Do you snore? It's often a sign of obstructive sleep apnea -- when you stop breathing during sleep.  It can cause high blood pressure, memory trouble, weight gain and depression. An 18-year study shows people who don't have sleep apnea live three-times longer than those who do.

Do you watch your calories? People who limit their daily intake to between 1,400 and 2,000 calories have hearts that function 15 years younger than they really are.

Another sign you'll live a long life is that your heart beats at about 60 beats per minute at rest. The typical heart beats between 60 and 100 beats per minute, but the closer you are to the lower end of that range, the less your heart has to work.
