The youngest part of the human body is the cerebellum, which is a part of the brain. The cerebellum can be up to 15 years younger than your chronological age.
This is because the cerebellum is responsible for motor control and coordination, and it continues to develop throughout childhood and adolescence. This means that the cells in the cerebellum are constantly dividing and renewing themselves, which keeps them younger than the cells in other parts of the body.
On the other hand, female breast tissue is the oldest part of the body, being up to three years older than your chronological age. This is because breast tissue is one of the first tissues to develop in a female body, and it begins to age more quickly than other tissues.
