You can give up the search for the fountain of youth... or at least the fountain of 20 years ago. Robin talks to health and fitness expert Bob Greene who lays out some small, simple steps that can take 20 years off!

Robin points out that the name of Greene's new book, "20 Years Younger" is "good marketing," because, "who doesn't want to feel, look and live like they're 20 years younger?"

Here are 4 "pillars" that Greene says are really important:
1. Get consistent, vigorous exercise
2. Get rid of empty calories in your diet
3. Take care of your skin. Exfoliate and use sun screen.
4. Probably most important... sleep. Get at least 7 hours.
