You've heard all the talk about watching what you eat and exercising for good health. Oprah Winfrey's personal trainer and best selling author, Bob Greene, has found a common sense approach that simplifies the task. Bob will be at a book signing later today.

You can attend a cooking demonstration as well at Schnucks on Manchester Road in Des Peres from 11:30 a.m. to 1 p.m. Bob will also offer advice on diet, exercise and the psychology of living your best life.
