Sleep (6x3)

Air date: Jun 28, 2015

The average adult spends more than 220,000 hours - or roughly 25 years - in bed sleeping. That's one third of your life spent in slumber!1 But what exactly is sleep - and why do we spend so much time doing it? In what could be our most ambitious Brain Games experiment ever, we keep 3 volunteers awake for 36 hours in order to answer just that.
