According to a popular old saying: If a nose is not born wrinkle, why is the skin not made of a nose? In this case, the problem is in the breasts. According to University of California researcher and professor Steve Horvath, on average, they are 2-3 years longer than any other body.
To determine the age of each body part, he analyzed nearly 8,000 samples of methylation patterns (the natural process that changes genetic material over the years) in 51 tissue and cell types. He then managed to unravel 353 age markers from the body. With the biological clock in hand, he found that each body part ages at a different speed.
