I see more and more of the bloggers/full timers leaving the lifestyle for what ever reason. Some because of health problems, some because they found the "perfect" spot they want to live. Got me to...
also remember full timing is different for many people. some keep traveling around the country...looking at new places. while other just stay in one or two places.
i know people in their 70s who have been full timers for a number of years. the bottom line is whatever you want to do, have the money and as long as you are healthy.
