As your body ages, you can expect gradual changes, at your body's own pace. How your body ages depends in part on your family (genetic) patterns of aging. But your lifestyle choices have a more powerful impact on how well your body ages. Fortunately, you can control your lifestyle choices.
Some of the following changes may apply to you. Others may not. A healthy lifestyle may slow many of these normal effects of aging.
Skin. With age, the skin becomes less elastic and more lined and wrinkled. Fingernail growth also slows. The oil glands gradually produce less oil, making the skin drier than before. You can slow skin aging by using moisturizer and protecting the skin from the sun with sunscreen and sun-protective clothing, such as a hat or cap.
Hair. It's normal for hair to gradually thin on the scalp, pubic area, and armpits. As hair pigment cells decline in number, gray hair growth increases.
Height. By age 80, it's common to have lost as much as 2 in. (5 cm) in height. This is often related to normal changes in posture and compression of joints, spinal bones, and spinal discs.
Hearing. Over time, changes in the ear make high-frequency sounds harder to hear and changes in tone and speech less clear. These changes tend to speed up after age 55.
Vision. Most people in their 40s develop a need for reading glasses as the lenses in the eyes become less flexible (presbyopia). It's also normal for night vision and visual sharpness to decline. Also in the later years, glare increasingly interferes with clear vision. Vision changes can affect your ability to drive safely. For more information, see:

Sleep. Changes in sleep and circadian rhythm occur as you age. You will probably sleep less at night, and you may not sleep as deeply as you did when you were younger. And it's more likely that you'll wake up during the night and/or wake up earlier in the morning. For more information, see the topic Coping With Changing Sleep Patterns as You Get Older.
