Read It! Scientists have discovered that people carry a staggering variety of bacteria on their hands. They found a total of 4,742 different species. Individual test subjects averaged 150 different types, with women averaging more types of bacteria than men. Scientists are not sure why but have offered several possible explanations. The difference may have something to do with acid on the skin. A man's skin generally has more acid than a woman's skin does, and bacteria do not thrive as well in more acidic environments. Another cause could be the differences in sweat and oil produced. Makeup use could also make a difference, as could skin thickness. Do It!
