In this episode, we sat down with Mark Aramli.

Mark is the inventor and principal engineer for the patented BedJet CCS. Mark's first engineering role was at United Technologies, builder of the space suit for NASA. His engineering responsibilities included the space suit primary life support system (PLSS), specifically elements relating to heating, cooling and climactic comfort of the interior space suit environment for the astronauts. But he's also worked on some other VERY interesting projects, as we learn in the episode.

My goal in the episode was to dive deeper on sleep than we have on previous episodes. Specifically, I wanted to learn about temperature, and how it effects our sleep. And, as always...Can we hack it? It's a great episode, and I know you're going to love it.
