A single elevated ESR, without any symptoms of a specific disease, will usually not give enough information to make a medical decision. Furthermore, a normal result does not rule out inflammation or disease. Moderately elevated ESR occurs with inflammation but also with anemia, infection, pregnancy, and with aging.
Between 65 and 81 percent of people can curl their tongues, and slightly more women than men can do it, studies find. The notion that a person's ability to roll his or her tongue is determined by a single dominant gene stems from a paper published in 1940 by geneticist Alfred Sturtevant.
A female blue tongue skink produces around six to nine babies at one point in time but it may be difficult to tell initially if the female lizard is actually pregnant or not. Sometimes it may happen that the female is overly aggressive and may instead hurt the male during mating.
