Mark Rober's video: Shark Attack Test- Human Blood vs Fish Blood

I personally got in the water and tested if Sharks had a preference of human blood vs. fish blood.

You'll also notice my doctor was Bob Newby from Stranger Things. Turns out there is a lot of personal info on a Covid result test and the part that says negative and positive wasn't easily readable so I photoshopped up something that solved both of those issues and didn't bother changing the date. No conspiracy here. I promise I actually got Covid and would have much preferred to actually filmed on the original schedule and not had to deal with it even with the private jet silver lining. Also, thanks to Discovery for putting my life in danger. begins August 9th.
