Back in the late '60's when I was a young lieutenant stationed at the large Army hospital in El Paso, TX, one of my many "additional duties" was being the Installion Mortuary Officer. My duties included going to the funeral home that the hospital had a contract with for the preparation of the remains of any active duty soldiers who died at the hospital. I only had to do this a few times, where I supposedly certified that the remains were properly embalmed and then properly dressed in the soldier's uniform with ribbons and insignia, if any, properly displayed. Seeing the process from the inside, so to speak, rather than as a mourner, was rather enlightening but not in a positive way.
The whole funeral business is a bit grostesque and a way to make money off the grief of the survivors. When Uncle Sam was paying the bill (for the active duty death) the amount we paid the funeral home was a tiny fraction of what a civilian would have to pay, and the funeral home still made a healthy profit. I remember one case where a young soldier had died in a motorcycle wreck, and in sliding down the road lost most of the flesh on his rear end. Laying in the coffin in his uniform it was very obvious that there wasn't much left of him in the midsection. When I pointed that out to the funeral director, he balled up some newspaper and stuffed it into the pants of the dead soldier and made it all look "normal".
When I die I will be cremated and the ashes interred at Arlington National Cemetary. I could really not care less but my kids or grandkids might want there to be a place where they could go to remember me (and/or my wife) if they choose to. This thread made me think about asking my kids now if any of them want the metal parts that will survive the cremation.
