Radon is estimated to cause thousands of deaths each year. Exposure to this invisible, odorless gas is the second leading cause of lung cancer in the the U.S. And almost one out of every 15 homes in the U.S. is believed to have high radon levels. Government experts recommend that all homes, whether new or old, be tested for radon. In multi-level homes, testing should be done on a level below the third floor. Luckily, testing is easy and inexpensive. Low-cost test kits are available at hardware and home improvement stores.

Scientists are now reporting that gum disease is a risk factor for stroke. Their research involved almost 10,000 adults ages 25 to 74. Those with inflammation of the tissues surrounding the teeth were significantly more likely to suffer a stroke. Why? Probably because of the effects of oral bacteria on other parts of the body.
