medical volunteers needed....

ok,so....the washington post has a special ad section.....for recruiting medical volunteers......makes sense that the numerous gov't research facilities would recruit locally.....for folks with no health problems as well as for niche groups.....cocaine-users between the ages of 18-45, folks with acid reflux, people who have hepatitis, folks who sleep too much and people who cannot stay asleep, people willing to test an anti-dengue fever vaccine, people willing to skip theircholesterol meds.....compensation provided.....a person lucky enough to have all the right conditions and/or gutsy enough to contract new ones could almost make a career out of medical 'volunteering'..
