According to a BBC news article “people who exercise regularly are less likely to get a cold” (BBC News, 2 Nov. 2010). The article concerns a study conducted in America. The study examined 1,000 volunteers, over a three-month period, asking them to report how frequently that they exercised for over 20 minutes with enough intensity to break a sweat. The findings showed that those who were physically active on five or more days of the week were unwell with a cold for about five days compared to nine days for those who did little or no exercise.

Did you know that some plants eat meat? These carnivorous plants usually grow in places where they cannot get enough nutrition from the soil. The plants look beautiful, but they can be deadly. The Venus flytrap, for example, closes on its prey, such as insects. Asian pitcher plants are sometimes large enough to hold 7.5 liters of liquid that attracts insects, but one sip, and they slide into the plant, never to be seen again. Bladderworts, a third kind of plant, are the fastest-known killers in the plant kingdom. They can suck up a mosquito larvae in 1/50 of a second. (by Prof. Carmella Lieske)
