At Westside Park, Pool Manager Claire Graves is the last line of defense. But Graves' last line of defense, considering melanoma afflicted her father and grandfather, is lots of sunscreen.

"And not even just life-guarding, throughout the day," says Graves. "Walking across campus to class. You know you can get a flip-flop tan on your sandals or on your feet."

Graves is a rarity, according to Dermatologist Dr. Miranda Whitmer. Whitmer says people at the pool, and everywhere else, should be wearing sunscreen all day, every day.

"Unfortunately I think there's a lot of bad knowledge about sunscreen out there," says Whitmer. "People don't understand that sunscreen actually is extremely important."

According to a recent poll conducted by the Marist Institute for Public Opinion, only nine-percent of people wear sunscreen everyday. In addition, about 40-percent of Americans never apply sunscreen before going out, and that percentage is higher in the south.

"If you're not sure that you're getting UV damage because you think all you do is walk out to your car and get into your office," according to Whitmer, "just roll your sleeves up. Every body's got that little bit of farmer's tan or that little watch band."
