Think back to when your parents were the age you are now. Scary. Very scary. They seemed so much older, and in a way they were. Today, midlife is the point at which we're just getting to the good stuff.

But as much as we feel younger at 40something than any previous generation, we still buy into age-old myths about midlife that keep us from living like the 30somethings we are inside.

From steamy sex to athletic potential to learning new tricks, here's the truth about five midlife myths:

1. Get HipsThat Won't Quit
Brittle bones don't have to be part of the aging process. Tell osteoporosis to take a hike.

2. Start Making Music
You can take up ivory tickling (and get good at it) at any age.

3. Discover New Skills
at Any Age
You may be set in your ways, but that doesn't mean you are slower to learn something new.

4. Great Sex Comes to Those Who Age
Getting older doesn't mean it's lights out for your sex life.

5. Redefine Your Fitness Potential
Don't assume your athletic performance takes a tumble at midlife.
