9. Paid Medical Testing

Man rules when it comes to testing on living beings, including its own kind. Science and testing has tempted man to go beyond the ordinary for ages, even if it means sacrificing a few lives in the process. Paid medical testing is not like the other contenders on this list. It is utterly legal and pays quite handsomely but there is one very big catch in it. It requires you to sign an obligatory contract which actually allows medical professional to test experimental drugs on you. It even makes you nod hesitatingly to bear all associated side-effects of the new drugs. Death too is mentioned among them, apart from seizures and vomiting. So, pick your experimenters wisely.
