During my 20+ year career in palliative care, I've had numerous experiences of families arriving at the hospital room to find their recently-deceased loved one already "zipped up" in an opaque plastic body bag, ready for transport to the morgue, or arriving in the morgue where an attendant will "unzip" the deceased. How utterly dehumanizing a memory for loved ones, and one that fails to communicate the respect due to decedents and their families.
This idea stems from a ritual in the hospice unit I directed at the VA, where every Veteran decedent was transported out of the unit draped with an American flag and we then all partook in a flag-folding ceremony.
I envision an alternative to the body bag -- a personalized "death garment" in which the body is placed shortly after the time of death, and in which it can reside through transport to the mortuary, crematorium, or other final destination. The death garment could be fashioned in a variety of formats, perhaps quilted together from meaningful garments from the person's/family's life, embroidered with a meaningful phrase, or even custom printed with meaningful photos. (I realize the last suggestion could be tacky, and/or conjure up images of Shutterfly discount coupons . . .)
