The ganges is the most sacred river in India and the Ghats the most sacred part. For this reason (and because it is there) lots of indians congregate on the banks of the Ghats each morning to wash, brush their teeth, have a swim and wash their clothes.
Because of its religious significance many cremations are completed on its banks and swept into its waters. You are only allowed to be cremated there if you have performed certain tasks and rituals in your lifetime. Otherwise and (less auspiciously) you have rocks tied to your feet and you are dropped into the middle of the river. Such is the number of droppings into the sea that the city had to turn to mother nature in order to address the number of bodies and now the ganges is home to a newly installed but thriving population of flesh eating turtles - yummy!
As such there was the unusual juxtaposition of a sewerage outlet pipe and a dead cow floating next to a chap brushing his teeth and his wife having a wash. What does not kill you makes you stronger I guess!
