On average, nearly 50% of Americans will make a New Year's resolution. Many of these resolutions will focus on health. But being healthy is more than just exercising, eating right and drinking water. Whether you are young, old or somewhere in between, prevention and early detection can significantly reduce your risk of illness, disability or an early death. As baseball legend Mickey Mantle once said, "If I knew I was going to live this long, I'd have taken better care of myself." Many of us probably feel the same about our current health status.
