Shopping for shades?
Ultraviolet (UV) radiation from the sun can damage your eyes, not just your skin. Choose sunglasses that block 99% to 100% of both UVA and UVB rays. Opt for wraparound sunglasses or closefitting sunglasses with wide lenses that protect your eyes from every angle. Keep in mind that the color of the lenses and the degree of darkness the sunglasses provide have nothing to do with the sunglasses' ability to block UV rays.

What's your high blood pressure risk?
High blood pressure has many risk factors. Some you can't control, such as age, race and family history. But don't throw up your hands quite yet.

Include physical activity in your daily routine. 3. If you drink, do so in moderation. That means no more than two drinks a day for men and one drink a day for women. 4. Learn healthy ways to handle stress, such as muscle relaxation and deep breathing. 5. Avoid excess salt in your diet.
