Paresthesia (Greek para- = abnormal, esthesia = feeling) is abnormal sensation on the skin that has no apparent physical cause (1). Paresthesia includes numbness and tingling, and can be temporary or permanent. Numbness is a decreased or lost sensation in the skin. Tingling is an unusual sensation in the skin. It is often described as feeling of pins and needles, tickling, pricking, creeping, skin crawling, ant crawling, and so on.
The orangutan (Pongo) is a great ape that has fur with a color between red and brown. There are two species of orangutan. They are from Southeast Asia. There are very few of them left, because loss of the jungle has reduced their habitat. There are orangutans on view at the Singapore Zoo.
The problem though is that humans will likely be on the other side of the glass. This is why you will often see them with their backs to the glass when they are inside. The life span for an orangutan is about 50 years in captivity and 35 â 40 years in the wild. They do seem to do quite well in captivity, especially those that are there from the time they are born. While we have learned a great deal about orangutans in such a setting, the desire of many to see them only in the wild continues.
