5.Your Immune System
Your body’s defenses lose a step in your 70s, which leaves you more vulnerable to illness. Vaccines don’t work as well as they once did for you, but because you’re susceptible to infection and viruses, it’s still important to get shots for flu, pneumonia, and shingles. On the plus side, allergies are less severe and autoimmune disorders are rare at this age.
6.Your Digestive System
Your stomach lining is more fragile, which raises your odds of having ulcers. That’s especially true if you take a lot of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs). Perhaps the most common problem at this age is constipation. Part of the reason is that your digestive system doesn’t move food through quite as well as before. Medications and lack of exercise may also play a role.
