Protect Your DNA
As you age, the ends of your chromosomes -- called telomeres -- become shorter. This makes you more likely to get sick. But lifestyle changes can boost an enzyme that increases their length. Plus, studies show diet and exercise can protect them. The bottom line: Healthy habits may slow aging at the cellular level.
Play to Win
An 80-year study found that people who are conscientious -- meaning they pay attention to detail, think things through, and try to do what's right -- live longer. They do more things to protect their health and make choices that lead to stronger relationships and better careers.
Here's one more reason to be grateful for your friends -- they might help you live longer. Australian researchers found elderly social butterflies were less likely to die over a 10-year period compared to people with the fewest friends. A look at results from 148 more studies shows a clear link between social ties and a long life.
Choose Friends Wisely
Your friends’ habits rub off on you, so look for buddies with healthy lifestyles. Your chances of becoming obese go up if you have a friend who adds extra pounds. Smoking also spreads through social ties, but the good news is that quitting is also contagious.
