I personally got in the water and tested if Sharks had a preference of human blood vs. fish blood. Get your first month of KiwiCo for FREE!!! www.kiwico.com/markrober
Point of clarification: A few people have pointed out the dates on the negative and positive Covid tests are the same. 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. #SharkWeek begins August 9th.
Catch ME in ShaqAttack Monday, August 10th at 9p ET only on Discovery.

Here is a link to that tiny exercise machine I was using the the jet. Luke (my shark expert buddy) invented it and it's really clever. He's launching a Kickstarter really soon- www.kickstarter.com/projects/whipr/whipr

Sorry this took awhile. I've got 8 absolute banger videos I'm currently working on through April 2021 but it turns out the Rona slows things down a bit. They will be worth the wait! For updates, follow me on social stuff @MarkRober.

So theres bans against public flights but none against private flights. Showing ones again, if you have enough money, the rules don't apply to you because the dollar has more value than the health and well being of a human life

Mark, I really love your videos and I do not want to come across as the spoiler of sorts but somehow I can't stand to see you wasting other creatures like the fishs. Just blending animals for the fun of it isn't all that funny - in my mind at least. And I can see beyond it, I get it, fishs were catched anyway, were going to be processed anyway etc. but still, this part just made me a bit sad.

The private jet part has convinced me that mark is just a child with money. Of course that arguably a good thing but either way I think we all would act like that on a private jet.
