As you age, your body goes through several changes. These include graying hair, skin becoming less elastic, and decreases in muscle mass and bone density. Osteoporosis is a significant concern, especially in older women, but it can also affect older men. Preventing osteoporosis involves strength training, good nutrition, not smoking, and limiting alcohol intake. Regular bone density tests are also important, especially for those at high risk. Healthy habits like regular exercise and a balanced diet can help slow down these changes.
