7.Your Urinary Tract
Your bladder can’t hold as much as it once did, and your muscles that support it have lost some strength. They might also squeeze when you don’t really need to go, which leads to an overactive bladder. All these things can send you to the bathroom more often. Many women in their 70s have trouble with urine leaking. Prostate trouble, which affects many men this age, can cause trouble going, too.
8.Your Vision
Your pupils react more slowly to changes in light, because your eye muscles are a bit weaker. You’ll need more time to adjust when you move between the indoors and bright sunlight. Some fine details are hard pick out, because there are fewer cells to send messages about what you see back to your brain. The lens gets thicker and more yellow, which makes it hard to see in dim lighting and makes colors less vibrant.
