Full show notes: https://bengreenfieldlife.com/tim2026 In this episode with repeat guest Tim Gray, you'll hear why the smartest biohackers are now removing more than they are adding, what paying attention to microplastics and environmental toxins in your own home and blood actually reveals, and why sulforaphane is making a comeback as a potential microplastic clearance tool. You'll also get a breakdown of the most interesting technologies coming to the Health Optimisation Summit this September, now in its first-ever three-day format, from hydrogen inhalation and bio-energy stimulation to hands-free vagus nerve stimulation, PEMF, STEMREGEN, and a full-body MRI trailer parked outside the venue.  Tim Gray is the founder and CEO of the Health Optimisation Summit, one of the world's largest health and longevity events, now expanding to multiple international locations. Known globally as The Health Community Guy, he is also the host of the Health Optimisation Podcast, an early-stage investor in breakthrough wellness brands, and the founder of London's first private hyperbaric oxygen clinic.
