Judging from our mail and blog comments some people sure have a lot of misconceptions about a lot of things. There’s confusion over, for example, human-caused climate change (it’s real), evolution (real), the age of the earth (estimated 4.5-ish billion years), vaccination (a life-saver), music (stop listening to AC/DC!) and spelling (prairie dog’s blog trolls suck at it).

In the spirit of shining a little Enlightenment into the Saskatchewan darkness, here’s a public service announcement by director Jason Wishnow about the five bodily fluids that can transmit HIV. Enjoy.

H/T Boingboing and Jason Wishnow.
