The more real reality shows

I picked up Season 1 of Survivorman on DVD a few months back, and have been gradually working my way through the episodes. I mentioned the show before on here, but I found an interesting article today regarding the usefulness of the show. To quote:

Snowmobiler Chris Traverse of Gypsumville, Man., is the latest to credit Stroud's show - also a big hit on the Discovery Channel in the U.S. - for saving his life thanks to the tips he picked up from tuning in regularly. ... A Utah couple also credited the show last month for helping them survive for 12 days after they got stranded in their truck in the snow.

Where else can you find video tips on how to kill and eat scorpions, for example?
