| The human body changes as it ages. The peak time for the human body is thought to be around the age of thirty. The body has an amazing capacity to renew, but cells can only divide a limited number of times. Thus, as we get older, our ability to repair damaged body parts decreases. Among the typical symptoms of ageing is the hair loss, poor eyesight and hearing and wrinkles. The hair growth slows down, and the hair becomes thin and weak. As for the eyesight, t he eye muscles become less flexible, which makes focusing on a range of distances more difficult. The cells of the inner ear are very delicate. They get damaged or die over time. The skin cells produce less collagen, and wrinkles form. However, it’s not al I bad. Today people live much longer than they used to live in the past Modem scientists are doing everything to slow down the complex processes of human ageing. |
