I have 24 days until I officially retire. No old enough for Medicare and I don't have any retirement insurance, so I will be paying independently for a few years. This was one of the reason my wife was initially hesitant to retire because of the cost of medical insurance, but an analysis showed we could retire, pay for insurance until medicare kicked it, fund the things we want to do and still shouldn't deplete our assets. So she was all gung-ho.
I understand about war zones, we had a retirement cruise scheduled to go to Greece, Turkey, Egypt and Israel but it was cancelled.
