According to legend, lore, and some fact, President Theodore Roosevelt may well have been the downright friendliest U.S. president we've ever had. One reason: On New Year's Day 1907, he set what was then -- and may still be -- the world record for the number of handshakes in a single day -- 8,150 to be exact.
According to those following the presidential campaigns of George W. Bush and John Kerry, there could soon be a new world record: Both men, it seems, are extremely fond of this traditional political "vote for me" greeting.
Like his favorite car, a guy's body needs regular checkups one that includes a screening for prostate cancer, otherwise known as a PSA test. The risk of prostate cancer goes up every year after age 50, that's why men need to take steps in preventing it, or making sure it's detected early.
The prostate-specific antigen (PSA) test is the best way to detect prostate cancer in its early stages. It's typically done along with a rectal exam, because most malignant prostate tumors start nearest the rectum...
The problem however -- in Roosevelt's day as well as now -- is that handshaking isn't exactly the healthiest way to win an election. Indeed, if experts are right, as we cruise head-on into cold and respiratory virus season, both Kerry and Bush could end up spending Election Day home in bed with the sniffles -- or worse -- as a result of those pre-election handshakes.
"Eighty percent of all infectious diseases are transmitted by contact both direct and indirect -- direct such as kissing, indirect such as shaking someone's hand," says Philip M. Tierno Jr., PhD, director of clinical microbiology and immunology at New York University Medical Center.
Though the germs don't ooze from our pores, he says, covering your mouth when you cough, wiping your nose with a tissue, even failing to wash your hands after using the bathroom can all leave germs on your skin that can get passed on during a handshake.
"If you eat or drink something without washing your hands, or if you touch your own nose, mouth, or eyes after shaking someone's hand, you can introduce whatever germ was on their hand, and now your hand, into the portals of your body," says Tierno.
Indeed, hand-to-hand contact can be such a potent way of passing germs that the CDC issued a special advisory which reads, in part, "The most important thing that you can do to keep from getting sick is to wash your hands."
Tierno agrees: "Frequent hand washing is the single most important weapon we have against disease."
