When he was born, Franco Villavicencio from Moreno, Argentina, looked just like any other baby boy. During his first year of life, however, his health began to deteriorate, seemingly for no reason. His parents had medical experts examine him and were told that the boy was suffering from a rare disease that was causing his body to age at an accelerated pace. This disease, named progeria, is the reason Franco Villavicencio, now 4 years old, looks nothing like a young child. Instead, his body is that of an old man. According to the doctors looking after him, the boy’s body is aging about 8 times faster than normal. This means that, when he turns 10, his body will that of an 80-year-old.
