That's very true Judith, my (paternal) grandfather volunteered to The Northumberland Fusiliers in 2015 and I have some of the shrapnel that was taken out of him, the rest stayed in permanently and caused him mobility problems as he got older.
Among all the other things I also have his army issue boot brushes so remember him whenever I polish my shoes. They have his army number and Ames & Bonner Co 1915 embossed in them and have only lost one set of bristles in nearly a century of use.
