When studying the anatomy of humans in biology textbooks, many authors marvel over the complexity of the human body. Attributes such as our opposable thumbs, bipedal mobility, and cognitive abilities are extolled; however, humans are at a serious disadvantage. We lack major appendages that would aid in daily living; they could greatly improve quality of life. One such appendage is a tail; understandably, some humans have grown accustomed to their current mode of living and would shy away from any change despite its advantages. For this reason, the tail that I am about to depict is prosthetic, allowing for attachment and removal when desired.
A tail would give a human numerous advantages, as long as it is constructed in such a way to allow for several functions. With the proper appendage on the distal end, it could perform as a third arm, a temporary seat, or simply an aesthetic addition.
