Don't take your heart health for granted.

A review in the journal JACC looked at data on more than 14,000 participants ages 30 to 79 in the decade-long National Health and Nutrition Examination Survey, and concluded that 20% of U.S. adults are at an increased risk of atherosclerotic cardiovascular disease in the next 10 years. And that jumps to 90% among adults ages 65 and older.

When they looked even further out — to 30 years in the future — they found that while more than two-thirds of people who are now ages 30 to 59 don't have cardiovascular disease, down the road 67% of them will develop it, and almost 90% of those now ages 45 to 59 will.

What does that mean for you today?

Even if you're heart-healthy now, chances are you're on the road to cardio woes. But you can take an exit ramp and head toward a healthier, happy future.

First, ditch all red and red processed meats, highly processed foods, added sugars, and excess alcohol. Instead, go for seven to nine servings of fresh fruits, veggies, and 100% whole grains each day.

Make sure you get at least 30 minutes a day of physical activity. I suggest 300 minutes a week of aerobics and strength-training, along with as much walking as you can do.

Most importantly, cultivate happiness with a posse, a sense of purpose, and play.
