Hello, and welcome to the kitchen. I wanted to invite you here today because last week we started off in my bathroom and kinda feel bad about that. And also because as I’m making lunch today I wanted to sort of use it as a lab. During this time in
In March of 2015, American astronaut Scott Kelly and his Russian colleague Mikhail Kornienko, began an unprecedented mission in space. They began a one-year term of service aboard the International Space Station, the longest tour of duty ever served on the ISS. Now, I imagine there’s all sorts of stuff
What potential disasters keep you up at night? Meteor strikes? Super Volcanos? World War Three? World war Z?

It has filled countless diapers, caused discomfort for any number of airline passengers, and it totally ruined the Dude’s rug, which really tied the room together, man. Anatomists call it micturition and I don’t know why because the rest of us know it as urination, which seems like a fine
It is time! We have arrived at the final conflict. The battle royale. A fight to the…well, hopefully not death, but a big fight anyway. It only seems fitting that we spend this, our last episode of anatomy and physiology, talking about one of your body’s last-ditch efforts to defend
