Progeria is a rare genetic disease characterized by the appearance of fast aging in children. The name itself is greek for "prematurely old." The occurence of progeria happens in 1 out of every 4-8 million, effects all races and sexes equally, and occurs all over the world. It is noticed around 18-24 months of age and the signs include growth failure, hair loss, lack of body fat, aged looking skin, stiff joints, hip dislocation, atherosclerosis, and heart disease. Children with progeria have very similar appearance despite different ethnicities and usually die of heart disease around the age of 13, usually having a life-span of between 8-21 years.
