There is a condition called progeria. In this disease the patients seem to undergo accelerated ageing. this means they develop some signs of being old like wrinkles, hair loss, loss of body fat and muscle and they have joint problems. This is caused by a genetic mutation in one of the genes responsible for the structure of our nucleus.
I suppose if something was to happen to speed up the damage that occurs in our lifetimes then this might potentially speed up ageing.
Why would you want to do this? I am struggling enough with turning 30 soon! not sure i want to get older too quickly!! 🙂
