I'm sixty and my coworkers often ask when I plan on retiring. I tell them I retired from the time I was 17 until I was 40 which is kind of true because I spent my time surfing, fishing, and traveling. I worked and supported my family, but we goofed off as often as possible. In my late thirties I went back to college, graduated, and started teaching school at 43. It worked out well and I intend to work until I'm 63 and call it a career. I like the idea of a travel trailer and a few years on the road.
