If you're like 67% of Americans, you're currently overweight or obese. If you're like 27%, your blood pressure is too high. If you're like a whopping 96% of the population, you may not be able to recall the last time you had a salad, since you're one of the hundreds of millions of Americans who rarely eat enough vegetables. And what you do eat, you don't burn off — assuming you're like the 40% of us who get no exercise. Most troubling of all, if you're like any parent of any child anywhere in the world, you may be passing your health habits to your children, which explains why experts fear that this generation of American kids may be the first ever to have a shorter life span than their parents do.
