What do you do when you're ready to retire from a successful career in Silicon Valley? Why not move to Africa and do volunteer work? Okay, this isn't the way most of us imagine spending our golden years. But Rick and Wendy Walleigh -- like so many baby boomers reaching the traditional age of retirement -- were too healthy, motivated, and interested in giving back to play golf for the rest of their lives. From Silicon Valley to Swaziland describes their experiences, from the challenges of day-to-day existence in an unfamiliar culture to the joys of helping people in poverty grow their own businesses. If you're thinking about transitioning to a more meaningful career, you'll find the Walleighs' story both informative and inspiring.
