What are the most common physiological changes caused by aging?
The most common physiological changes with aging, starting from the top of your head, is getting gray and loss of hair. In your eye, the amount of light coming in your eye decreases, so it’s harder to detect colours and you may need reading glasses. With your nose, you can have problems with smell. Concerning your ears, you have decreased hearing. With taste, you lose your taste ability with aging. Your joints become stiffer, your skin changes and becomes less flexible. Your heart can’t beat as rapidly and your lungs don’t expand and contract as efficiently. Your kidneys don’t secrete urine as well as they used to either. And that’s just the short part of the long laundry list I could give you about physiological changes with aging.
