Actually upon further thought, I think that pharmacutical companies have a very aggressive and good marketing team.
They put these very general symptoms in comercials like :
“Do you have semi-frequent headaches? Do you seem dizzy and sometime feel like vomiting? Does your skin sometimes discolor from normal? If not, try Proagra!!!”
They MAKE you think that you need this shit, when in fact, doctors know wtf is up, and they will prescribe you shit. Instead of you going to your doctor and telling him that you want to be prescribed shit.
