This school science experiment will make you want to wash your hands: ‘So disgusting’

With cold and flu season upon us, a couple of elementary school teachers decided to try a hygiene science experiment that they hoped would encourage students to wash their hands and spread fewer germs. The results were eye-opening.

“We did a science project in class this last month as flu season was starting,” Jaralee Metcalf, a behavior specialist at Discovery Elementary School in Idaho Falls, Idaho, wrote in a Facebook post, which has since gone viral with more than 64K shares. “We took fresh bread and touched it. We did one slice untouched. One with unwashed hands. One with hand sanitizer. One with washed hands with warm water and soap. Then we decided to rub a piece on all our classroom Chromebooks,” adding that the school normally sanitizes their computers but didn’t for this experiment.

Your Christmas tree might be making you sick. Here’s what you should know about this seasonal syndrome

Feeling wheezy around the holidays? You may have “Christmas Tree Syndrome,” an illness caused by moldy firs.

Dr. Lawrence Kurlandsky, an allergist-immunologist in Syracuse, New York investigated the idea after observing that cases of respiratory illness reach “epidemic peaks” one week before and one week after December 25 for children and adults, “often raising suspicion that a live, indoor, coniferous Christmas tree may be playing a role,” according to a study published in June 2011.

Kurlandsky tells Yahoo Lifestyle, “Many molds can be found on in-home Christmas trees including the four most common molds that people may be allergic to. The article was to make people aware that the presence of an evergreen tree in those during the Christmas season could contribute to respiratory illness in susceptible, allergic people, especially children.”

This is the age people find the most meaning in their lives, study shows

Searching for meaning in your life? It may take longer than you think to find it.

A new study, published in the Journal of Clinical Psychiatry, looked at more than 1,000 adults ages 21 to more than 100 years old, who live in San Diego, Calif. They were given what’s called the Meaning in Life Questionnaire, which assesses both the presence of meaning and the search for meaning.

The researchers found a U-shaped curve, showing that people at age 60 reported the highest presence of meaning and lowest in searching for meaning — in other words, they had found their purpose. “The most common pattern is that as our levels of meaning in life are higher, we tend to search for meaning less,” Michael F. Steger, PhD, director of the Center for Meaning and Purpose and professor of counseling psychology and applied social and health psychology at Colorado State University, tells Yahoo Lifestyle. Steger, who was not involved with this study, researches meaning and developed the Meaning in Life Questionnaire.
