How long does a coffin last?
How long does a coffin last? Eventually these too will disintegrate, and after 80 years in that coffin, your bones will crack as the soft collagen inside them deteriorates, leaving nothing but the brittle mineral frame behind. But even that shell won’t last forever. A century in, the last of your bones will have collapsed […]
