Walking is the single most complex motor function of the human body. Even scientists, who have been studying it for more than 2,000 years, don't yet fully understand it. It involves more than half of the body's 650 muscles and 208 bones, plus more than half of all the ligaments and joints. That's just to take a few steps.

LITTLETON, Colo. -- A dental office X-ray reveals a four-inch nail embedded in the skull of Patrick Lawler, 23, which was removed at Littleton Adventist Hospital in suburban Denver. Lawler unknowingly shot himself with a nail gun Jan. 6 while working in Breckenridge, a ski resort town in the central Colorado mountains. The accident left Lawler with what he thought was a minor toothache and blurry vision. When painkillers and ice failed to stop the ache six days later, he went to a dental office where the nail was discovered.

And, when the doctor said I didn't have worms any more, that was the happiest day of my life.

If you notice the spider on a wall, often the Salticus scenicus, it seems as it mocks gravity. It jumps of the walls and falls back on it several centimeters further instead of falling down. If you watch the spider carefully, you can notice that it always releases a lifeline when it jumps. If the jump fails it can crawl back to its original position and it prevents the spider from falling down.
Jumping spiders do not make webs to catch prey. Instead, they hunt their prey on foot. They do use silk to make a small shelter under a leaf or bark.
To catch prey, Jumping Spiders sneak up on it... they can leap great distances when you consider their size.

HONG KONG (Reuters) - A Hong Kong hiker washed her face in a freshwater stream, not noticing that leech had wormed its way into one of her nostrils, according to the Hong Kong Medical Journal.
Unaware she was playing host to the creature, the 55-year-old woman only consulted a doctor when her nose started bleeding intermittently about two weeks later...
The first doctor the woman saw could not find anything wrong and it was only when she visited a second doctor that he saw the five-centimeter (two-inch) leech peeking out of her left nostril.

GW&M: A sensitive issue that people are often reluctant to discuss concerns the cultural differences in personal hygiene. What are your own experiences?

NETTERFIELD: My husband, like almost any American, showers at least once a day, every morning. Most days he also showers after exercising. That makes two showers every day. In Germany people bathe once a week on Saturday evening.

GW&M: So the old US joke about bathing once a week whether we need it or not is actually the German practice?

NETTERFIELD: I still to this day do not shower regularly every day. I wash in strategically important places every day, but usually will only bathe once a week. When my mom visits us here in the US, she even notices that most people here will not smell like old sweat, but like they are freshly washed. When you are in an elevator in Germany or any other closed confined room, you will smell stale sweat from unwashed bodies. It's just what people are used to.
