...Drugs, researchers recruited 42 adults: half were between the ages of 50 and 74, and half were aged 25 to 35. The participants were given either alcoholic drinks - roughly equivalent to a couple of glasses of wine - or placebo beverages, then asked to perform tasks designed to test their motor skills. They were also asked to rate their level of intoxication on a scale of 1 to 10. While the older people were more impaired by the alcohol, they also consistently underestimated their drunkenness. That may be because over the years, people become inured to the effects of social drinking...
...Nixon was surprised by the results. "We often want to say that if we are below a legal limit, there are no consequences. That just isn't true," she says. Though older participants considered themselves only marginally impaired, on average, they were about five seconds slower in completing the motor-skills tasks. "That doesn't seem like much," Nixon says. "But it's an awfully long time if you're moving your foot from the gas to the brake...
...lubrication," says Nixon. But on the down slope, as the alcohol is metabolized, its effects are more sedating. To measure the relationship between people's actual and perceived impairment along this continuum, researchers tested subjects twice, at 25 min. and 75 min. after they'd begun drinking. The two motor-skills tasks used to measure actual impairment were akin to connect-the-dots, but slightly more complicated. The first test simply required participants to draw lines between numbered dots in order; the second required them to alternate between numbers and letters in order as they connected the dots.

...launched goswap.org whose 10,000 or so users are trying to swap not only real estate but yachts and motor homes too. Alice McLaughlin, a caregiver in Canaan, N.H., is close to inking a deal to swap her two-story log home for a place in Hawaii in which she could care for people who otherwise must be in a nursing home. "So far, this [site] has seemed like an easy way to get a win-win situation," she says...
Researchers monitored 872 children from birth to three years of age in terms of how many hours they spent in front of a television screen. The findings revealed that children who watched educational programs were no more adept in vocabulary or visual and motor ability tests than those...
