Now in our 14th year of full time traveling, our exit plan is to die out here, wherever we happen to fall. When one of us dies, the other will downsize and carry on, as capable. If incapable, there are choices in place that do not involve lingering unhappily.
Nope, no plans for an escape location. Absolutely no compelling reason to abandon the lifestyle. If we'd wanted to sit in one place and watch our lives ebb, we'd have stuck with the sticks and bricks 13 years ago.
Every life - and death, is different. Only you can decide what is best for you.
