In Seattle, WA researchers are trying to get approval for an amount of about 2 grand per test subject to be paid to people who are willing to get and be treated for malaria.
They chose Seattle because it's full of "altruistic" and generous people who are willing to sacrifice themselves for a truly greater purpose. By which I mean it's full of Heroine addicts who have no money. 2 grand's a lot of Heroine man...
I've heard its also quite a bit of heroin, but I'm sure you could get several nice young ladies from the corner dressed up in Wonder Woman costumes for $2,000.
