When I met Tim Gray aka Tim Biohacker roughly four years ago at a conference, I was quite sure he would make some serious impact in the world of Biohacking and Health Optimization.   To keep a long story short, I was right but still understimated the impact he would make. With founding the Health Optimization Summit  (HOS) in London, Tim managed to bring nearly all  the superstars from the US to one single conference in London and I am quite sure, once the black plaque has been officially ended and traveling internationally will become possible again, the next HOS in London will be even better than the first edition. But for the meantime, meet Tim Biohacker, and learn about HBOT, Grounding and its impact on the immune response...
