I'm back from LA now. What a trip. The Bulletproof Conference was a chance to reconnect with friends and meet some new ones too.  Many of the recommendations at the conference are pretty much the complete opposite of what we are taught growing up about wellness. It can seem overwhelming. Butter is okay, nicotine’s okay too (but certainly not smoking), and so on. But many other hacks seem to be a mixture of the futuristic and the primal. As well as eating plenty of veggies, most of those gathered in LA are big fans of meditation and getting some natural sunlight in the morning. Hardly anything particularly revolutionary about that. Light is a drug - eh? Light is a big theme at the conference. Some speakers talk about how light affects your brain like a drug. Experts and exhibitors alike look at adapting your environment so that the lights help you to perform at your best, especially if you live somewhere cold, damp and grey, (sound familiar?). As well as our dearth of natural sunlight in a northern hemisphere winter, some of our offices and devices apparently emit five times more blue light than daylight, which really messes with our sleep and circadian rhythms. Today I'm with Scott Nelson, a man who knows all about light, and in fact has invented a device that is rather cool. And man, it's bright! Check out the podcast for more, and Scott's website here.
