In our family we were shocked a year ago when one of my wife's big brothers (a mere five years older than me) was felled on holiday, by an ultimately fatal heart attack. Weeks later his body arrived back from abroad in ,a zinc lined box embalmed of course as required by the international rules -- written, I presume by the industry.
The funeral industry is very cunning, with a mastery of softly selling the appearance of life via embalming and makeup. when I go I want a closed coffin funeral with a mushroom suit if legal and definitely no embalming etc unless I am abroad when I want to be buried where I die or if cheaper cremated and my ashes returned
