I try to dedicate at least two hours of my day to my body. That means I work out everyday, but I also enjoy running (usually twice a week, 10 Km each) and recently began practicing Muay Thai.
Learning German
Reading (at the moment: Sapiens: A Brief History of Humankind and Gödel, Escher, Bach: an eternal golden braid)
I like watching some TV shows, but Sherlock and Westworld left me orphan for now
As many of us here, I read a lot about tech too (probably should be more disciplined about this one)
Last, but not least: every once in awhile I try to benchmark alcohol effects on my cognitive system :P
