Now that's the first topic in my entire life which has direct relevance to me
I being the owner of a pharmaceutical company, i understand how important these clinical trials are for testing a particular drug newly discovered and for that we need a subject/agent who would volunteer to let us administer the drug on them. They are heavily paid for this and in return we get the exact results of the drug. The subject is kept in 24 hours surveillance along with all possible facilities including medical checkups, the expenses of which are all borne by the company. Without this activity, no new drug can be tested and commercially formulated to make reliable medicines which all you at some point of time use to heal yourself from various ailments. So again, no job is good or bad. Everything keeps some relevance.
Lab humans do exist . . . Occasionaly, students earn 
by being test persons for a potential medication which is still in the process of development. Would U take pharmaceutic products which effects are not entirely predictable for the sake of getting paid for it?
