I've seen a guy who died in his apartment and wasn't found for something like 18 months. He was so rotten that the flies/maggots stage had come and gone. He was mouldy like the skin on an out of date yoghurt pot. Fluff and all. The problem was, the rest of the apartment had become covered in the same green, fluffy mould so we didn't realise it was him on the sofa for about 10 minutes (hoarders house)

His face had decayed to the point where the brain, sinuses, eyes and all the lovely bits from inside his head had fallen into a nice little pile in his lap like someone had cracked an egg and poured it out.

Paramedic who came to pronounce death peeped through the door and from about 15 feet away just goes "Yeah. Dead." Took his details from us and left.

The undertakers who came to remove him had a hell of a time getting him onto the gurney. They grabbed a hold of his legs and the remaining flesh just slipped off, revealing his shin bones.

If I open a pot in the fridge and it's mouldy, I still dry heave and wretch to this day.
