6) Suicide Doctors
Sometimes people are fed up with life and just want to stop living. So, instead of committing suicide and dying in horrible conditions traumatizing a lot of people around them, some people just decide to go the a suicide clinic and choose euthanasia.

7) Selling Dirt
An Irish man was thinking about all the immigrants that went away and stopped living in Ireland. So, he decided to make some money with them by selling dirt, marketing it as dirt to sprinkle on their graves when they die – Irish dirt, from their homes. His sales have boomed with this idea.
8) Eating
Some people are able to make a living from simply eating. Before the Internet boom, watching people eat was a sexual fetish that people kept to themselves, but after the boom, people started sharing their desires and the business exploded into something very profitable.

funny though!
