Accelerated aging disease

Accelerated aging disease is when a person gets older much faster than normal. Instead of aging normally over a period of 80 years, a person with this disease might age up to 15 years in one year! This is because their cells don't work like normal cells and they can't repair themselves as well as normal cells do. People with this disease can become very weak, their bodies can start to look older and they may get sick more easily. It is a very serious condition and there is currently no cure.
