Humans are bipedal primates that usually grow up to six feet tall, some genetic diseases can stunt or extend this growth. Humans have sparse amounts of hair on their heads, and the males grow facial hair when they get older. Humans will vary in skin color, height and weight depending on which region they are native to.
Humans are highly intelligent and are capable of forming languages and communicating with others. Human beings, more than often, don't agree with one another, this leads to fights and vice versa. Humans are noted of their lack of constructive criticism and co-operation at times.
In the past, humans lived on average to about age 80. However, advances in medical technology has allowed them to reach age 150. Humans have a carbon-based power-grid, and are attempting to switch to a nuclear/wind/water-based one in order to conserve resources.
