For those who might b interested in Benedict Cumberbatches breathing techniques, a word of caution. Your body is actually controlled by the amount of CO2 u have, not the O2. If u breathe in deep and fast several times, ur hyperventilating, ur blowing off too much CO2. Your body’s automatic response is to stop u from breathing so u pass out. It also means theres less O2 going to your brain, and who needs that. Stay safe.

He really needs to start listening to the right people đŸ¤¦…
