Sure, growing old means becoming slower afoot, fatter around the middle and grayer up top. But getting on in age also involves enduring hurts that won’t heal, altering sleeping patterns, even looking at the world with a different viewpoint than you had 20 years ago.

Just in time for Forever Fit’s annual end-of-the-summer Geezer Guide, I polled a passel of 50-somethings about what to watch for with the onslaught of advancing age. Read on and see how many of the following statements ring true for you. Then use the Scorecard to rate yourself.

You know you’re getting old when viewing sports on TV is more fun than playing them.

You know you’re getting old when at least one body part hurts every day.

You know you’re getting old when beachcombing and gardening become your preferred fitness activities.

You know you’re getting old when all your doctors look younger than you do, and you regularly visit more than one.

You know you’re getting old when at least three different physicians proclaim your knees “hopeless.”

You know you’re getting old when your major monthly expense is for prescription drugs.

You know you’re getting old when your children start wearing your leftover high school and college clothing so they can look retro.

You know you’re getting old when those same clothes fit your kids a lot better than they fit you.

You know you’re getting old when eating anything “hotter” than red, yellow or green bell peppers makes your stomach do flip-flops.

You know you’re getting old when it’s more painful to throw a softball than get hit by one.

You know you’re getting old when that 25th reunion is from your college, rather than your high school alma mater.

You know you’re getting old when your age is almost as high as your pulse rate.

You know you’re getting old when you can’t remember your age on your birthday (and you don’t care to be reminded what it is).

And finally, you know you’re getting old when being able to blow out all those birthday-cake candles with one breath is what you wish for.Scorecard How many of the statements can you identify with? Rate yourself as follows:

10 or more: Bona fide member of the over-the-hill gang

5 to 9: You may look youthful, but you’re more vintage than vigorous

Less than 5: Don’t kid yourself, geezerville is closer than you think
