Why do mosquitoes prefer to bite some people over others? What happens to the body when it faces extreme cold? Why does removing hair from certain parts of our bodies hurt so much? Why does it hurt so much to get pricked with a needle? Marley will be our guide in this scientific adventure. With him, we will ask very common questions (plus some not-so-common ones), which we will try to solve by experimenting on our own bodies. Well, more like other people's bodies. We will do so with the help of our guinea pigs who are willing to subject themselves to empirical research: the testers. In the name of science and using humor as a tool, the show aims to answer these questions of everyday life that we have always wondered about in an unusual, but fun way.
