LOUIE TODAY: Vitamin D cure, Straight Edge, and adults only

Osteopath .John Vargo, the physician at the Mahoning County Jail, returns to chat about the importance of vitamin D along with Dr. James Dowd, author of "The Viatmin D Cure. " Louie, Vindy.com's news radio partner, will reveal the result of his vitamin D test and discuss the results with the doctors. it's long been known that a healthy Vitamin D level is related to strong bones, but several recent peer-reviewed scientific studies have clearly shown that Vitamin D also decreases our risk of getting overweight and developing high blood pressure, diabetes, heart disease, arthritis, cancer, and other health problems.

Also, Louie will talk with researchers from National Geographic magazine about a growing youth issue called the Straight Edge. It's a new gang that deals with the minefield of drugs, sex, violence, and peer pressure ijn an extreme way They are being classified as a violent gang in areas such as Salt Lake City and Reno, but they aren't like any other gang you know: they reject drugs, drinking, smoking, and even casual sex. They're rebels against a society in which everything goes. National Geographic goes inside this growing youth movement caught between being a refuge for Americas kids and a dangerous gang wanted by authorities.

And on a part of the show for adults only, Mary Roach returns, this time to talk about "Bonk: The Curious Coupling of Science and Sex." The study of sexual physiology—what happens, and why, and how to make it happen better — has been a paying career or a diverting sideline for scientists as far-ranging as Leonardo da Vinci and James Watson. The research has taken place behind the closed doors of laboratories, brothels, MRI centers, pig farms, sex-toy R&D labs, and Alfred Kinsey's attic.

Mary Roach, labeled "the funniest science writer in the country" by Burkhard Bilger of The New Yorker, devoted the past two years to stepping behind those doors. Can a person think herself to orgasm? Can a dead man get an erection? Is vaginal orgasm a myth? Why doesn't Viagra help women — or, for that matter, pandas? In "Bonk, "Roach shows us how and why sexual arousal and orgasm, two of the most complex, delightful, and amazing scientific phenomena on earth, can be so hard to achieve and what science is doing to slowly make the bedroom a more satisfying place.
