I've heard a podcast with him (London Real) and 2 days ago while waiting on a bus after my 14hour shift at work I felt like shit. Literally sat 14 hours in front of screen, didn't move a bit the whole day...and then I remember his crazy deep breathing technique....so I went for it, 30 fast breaths - in, out, in, out, in out....
And I almost fainted :DD Really, the sudden amount of oxygen that got to my system and brain was too much, I couldn't see anything for like 3 seconds :D Eventually it went away and it was suupercool experience.
I guess I'mma implement it in the mornings to get going, but probably just 20 breaths to not faint back to sleep :D
(upvoted, although my votes have zero value :DD dunno why, Im 90% charged :D)
