Each winter, millions of people suffer from the flu. Flu-the short name for influenza-is caused by viruses. Viruses are very small germs. Some viruses can spread easily from one person to another. They cause illnesses or infections like the flu.
For some people, flu is a mild illness. For older people, especially those who have health problems like diabetes or heart disease, the flu can be very serious.

Since he retired, Edward dreads going to bed at night. He's afraid that when he turns off his light he will just lie there with his eyes open and his mind racing. "How can I break this cycle?" he asks. "I'm so tired-I need to get some sleep."
Just like Edward, you want a good night's rest. Getting enough sleep helps you stay healthy and alert. But many older people don't sleep well. If you're always sleepy, it may be time to see a doctor. You shouldn't wake up every day feeling tired.

Irene is retired, she loves to work in her garden. Because she has always spent hours outside, she thinks the heat and humidity of Midwestern summers don't bother her. Then last year an unusual heat wave hit her area. Every day the temperature was over 100° F, and the humidity was at least 90%. Five days into the heat wave, her daughter Kim came over because Irene sounded confused on the phone. Kim found her mom passed out on the kitchen floor. The ambulance came quickly when called, but Irene almost died. She had heat stroke, the most serious form of hyperthermia.

Anyone at any age can have a drinking problem. Great Uncle George may have always liked his liquor, so his family may not see that his drinking behavior is getting worse as he gets older. Grandma Betty was a teetotaler all her life-she started having a drink each night to help her get to sleep after her husband died. Now no one realizes that she needs a couple of drinks to get through each day.

At age 75, Sheila thinks she's a very good driver. And she wanted to stay that way. So she got her eyes and hearing checked to make sure she can see and hear well enough to drive safely. Then she signed up to take a driving course for older drivers at her local automobile club. Will all this effort guarantee Sheila's road safety?

A simple fall can change your life. Just ask any of the thousands of older men and women who fall each year and break (sometimes called fracture) a bone.

"Arthritis" is not just a word doctors use when they talk about painful, stiff joints. In fact, there are many kinds of arthritis, each with different symptoms and treatments. Most types of arthritis are chronic. That means they can go on for a long period of time.
