Muscle: As your male hormones begin to decline around middle age, you’ll naturally lose muscle mass. Although your body will respond less dramatically to strength training as you get older, it’s important to keep it up over the years because it can slow muscle and bone loss, and actually boost testosterone levels.
Just so, at what age do the processes of aging begin?
Some systems begin aging as early as age 30. Other aging processes are not common until much later in life. Although some changes always occur with aging, they occur at different rates and to different extents.
In this way, what is the normal aging process? Aging is a gradual, continuous process of natural change that begins in early adulthood. During early middle age, many bodily functions begin to gradually decline. People do not become old or elderly at any specific age. Traditionally, age 65 has been designated as the beginning of old age.
