If you died in your home. How long do you reckon before your body is found?
Only one person I know bothers to trek it to mine unannounced but most people will call me and if I don't answer, will just assume I'm blanking them. Same with family. So I don't think they'll check at my house.
So you reckon you'll have to stink up your neighbour's plumbing with your rotting corpse before anyone notices?
