Quiz: Test Your Knowledge About Healthy Retirement

To lower your risk of Alzheimer's disease, flex your gray matter by solving a crossword puzzle or reading a book. But make sure you also get up and move.

Research shows that almost any moderate exercise (like walking, swimming, or biking) lowers the risk of mild cognitive impairment (MCI). That's a condition that often happens before Alzheimer's disease. People with MCI get Alzheimer's at a rate 10 times higher than the general population.

People who retire in their early 60s may not be as healthy as those who stay in the workforce. Those who keep working part-time or as a temp tend to have fewer major diseases and better mental health.

Experts don't know exactly how work or even a particular job helps you stay sharper. But having somewhere to be, something to do, and being social may have something to do with it. And you’ll have a little more money for your nest egg.

On average, men today will be retired for about 18 years. Guys who retired in the 1960s could expect to enjoy less than half of that. The reason? Americans still retire around the same age, but we're living longer overall.

Even though you're ready to retire, it doesn't mean you're too old for sex. While some people report a dip, it isn't huge.

It seems to affect men more than women. Twenty five percent of men say they have less sex than before. Only 19% of women say the same. To keep your love life healthy, use some of your newfound time to reconnect with your partner. Find activities you can enjoy together that can breathe new passion into your relationship.

Go ahead and offer to watch your grandchildren if you enjoy spending time with them.

While caring for youngsters can cause health problems for some grandparents, it's not always the case. People who see their health decline as a result of caring for their grandkids are the exception, not the rule.

The AARP says 9 in 10 Americans plan to stay put when they retire. But if you're thinking of moving, you might want to consider health care, chances for volunteering and part-time work, and the art and culture scene.

There are many online rankings and tools that can help you choose your best retirement city.

You might be surprised, but when it comes to retirement, only 32% of people over 55 want to move within 20 miles of their kids and grandkids.

It's really a matter of personal choice. Some people look forward to being closer to their family, but others prefer the adventure of finding new social circles.

Even if you haven't been as active as you'd like during your working years, that doesn't mean you can't get moving after retirement. In general, people actually tend to become more active after they retire.

In one study, women added more than half an our to their workout time each week. Men increased their activity by 42 minutes a week. So get up, get out there, and enjoy! Exercise not only feels good, it's good for your health.

You can sleep in. You have more free time during the day. Having that extra glass of wine sounds like a good idea. Right?

While at least one survey found that retirees tend to drink more and heavily, it doesn't mean you should. For your health, try to stick to just one drink a day for women and two for men.
