Tobacco-free snus / pouches
The episode on nicotine was great, very informative. If we want to try nicotine intermittently to aid focus, would the best option be tobacco-free snus or pouches? The "healthy" alternatives to smoking or harmful pouches/gums were unclear to me. In Europe, nicorette is only available on prescription to quit smoking, so not an option for most Europeans. There are, however, tobacco-free pouches available. Are these less harmful than their tobacco counterparts? Both contain nicotine.
Benefits of various aerobic zones
Good Day! I'd like to get some clarity on the degree of benefit to sticking to only zones 2 and 5 for aerobics, in the context of "Am I wasting valuable time and energy exercising in zones 3 & 4?). Peter Attia in particular is very vocal on this and almost seems to eschew zones 2 & 4 (even referring to them as "garbage" zones in one interview). My wife LOVES to jog 30 minutes x 5-6 days per week, but she's questioning herself because she spends most of that time in zone 3/4. I did notice from your protocol that you do one day each week in zone 3-4 as well. Thank you for all you do!
Neuroscience behind energy healing?
non-conventional medicine like acupuncture and reiki are all around in hk. the older generation of my family tend to seek for some really traditional-look, sometimes unhygienic, medical centres in the city, believing the elder practitioners have enough experience to heal us... briefly browsing around online, these types of 'medicine' looks to be playing with biofeedback or hypnosis... the energy healing reading, Healing, Intention and Energy Medicine Science by Wayne B. Jonas and Cindy C. Crawford, looks legit as well. any insight from your lab or colleagues? thank yoU!
