If someone drowned at sea a couple of hundred years ago they’d either start to decompose immediately or they’d get eaten by fish or other scavengers. The bones would eventually sink down to the seabed and either be slowly buried by marine silt or broken down further over the years, but the flesh would one way or another eventually become water, which would evaporate into clouds and then rain down upon the earth once again to become plants and flowers.The flowers in your garden could once have been famous pirates such as Blackbeard or Calico Jack.
