Query: Surprisingly Great !!

I'm so impressed with Bike for Life that I bought another one. First, I bought one for my dad's birthday - he's 51, rides like he's 21, and always says he plans on living to 101. The longevity information is right up his alley, but this book is so packed with other great info and is so fun to read that I bent-up too many of the pages reading it and had to order a fresh one for him. Then I forced my bike-crazy husband to read the " Rolling Relationships" chapter #12, which was so illuminating and entertaining that it seems like it could be a book all it's own. Thanks to that, we're going to get a tandem.There's more surprises throughout the book. I didn't know about that osteoprorisis problem, but now I'm going to the weight room-my husband, too.. Then the in-depth interviews--I never heard of Missy Giove before this, but now she's my hero. It's like the Bicycling magazine editor said: You simply don't expect to get something interesting in a mere bike book. But it is.
