49 Love

If you were trying to defy the aging process, wouldn’t you take the advice of a tennis legend who at 49 is still playing Wimbledon, and who can hustle a neon green tennis ball over a net at what may well be the speed of light? Martina Navratilova's Shape Your Self: My 6-Step Diet and Fitness Plan To Achieve the Best Shape of Your Life doesn’t mince words. She's a shining beacon of fitness, and she's ready to tell you how you can stop time from passing, the clock from ticking, and keep you looking (and feeling!) younger than a fabulous Hollywood “It” girl. 

Even L. Lo is looking a bit ragged these days (can you believe she’s already 20?), so learn the secrets of the Grand Slam of Health when Martina brings it to the Harvard Coop, 1400 Mass Ave, Cambridge | 10 am | free | 617.499.2012.

Of course, none of this means she isn't down with the senior stuff. In a recent interview with ESPN, Navratilova declared: "Now that I'll be collecting AARP discount, it's time to move on with life." Reap the benefits.
