This was the tune played by the british army bands after the final british surrender to the yanks, as they filed down after the negotiated end of hostilities (brits kept personal arms etc). It reflected the feeling, after a century of victory against the french and various colonials, that any defeat for the British was unnatural. I've often felt the same thing (world turned upside down) on a personal scale since I retired. I sometimes find myself (as now) staying up all night and sleeping all day. This doesn't bother me particularly, I'm just curious: do others experience this? And is insomnia part of aging? In one sense, not working is fantastic. In another, I'm unmoored.
