A magnificent 5. My parents moved house once. I moved out into a flat, met first wife and we bought a house. We then moved twice more, the last being retirement when I was 55, 17 year ago. First wife died some years back, and current wife still lives in UK, while I am in La France Profonde - we used to visit each other before Covid, but now it's only Zoom! - and expect to die here, but preferably no time soon!
