Diving down into a hole of sludge with his bare hands, spare a thought for this poor sewer cleaner in Bangladesh who has one of the world's least desirable jobs.
The man, who is an employee of the Dhaka City Corporation, has to unblock the city's sewer lines without any proper safety equipment.
He often has to go dig around underground with only a long stick to help him and with no mask to protect him from the poisonous fumes the sewage emits.
Scooping out liquid filth with his bare hands, the hardy worker has the thankless task of clawing out blockages in the bustling Bangladeshi capital.
Dhaka has a population in excess of 14 million and has recently been hit by major floods caused by heavy rains and an insufficient storm drainage system.
Despite the alarming rise in the number of deaths of manhole workers, cleaners are still not supplied with sufficient equipment and regularly have to enter the dirty sludge topless.

Dangerous: Workers are often surrounded by cockroaches, and have no masks to protect him from the poisonous fumes
Tough job: The worker has to clean the muck from the drains in Dkaha with his bare hands
In up to his neck: The worker goes deep into the hole knowing he could drown if caught in a sudden rush of sewage
