Eye Masks for Darkness

Are eye masks sufficient for the darkness requirement? Are they less efficient than being in a room of darkness? Are they better than nothing when you can’t dim the lights - i.e. sleeping on an airplane? Follow up question: how would one go about sleeping on an airplane?

Nicotine and serotonin

Hi, could you talk about the effects of nicotine smoking on serotonine?

I am interested in enzymes and cellular pathways like nrf2 and mtor

Can you do a segment on these and other cellular pathways, and discuss how they regulate cell growth, or don't, and the implications for these and other pathways for common diseases: cancer, ms, diabetes... It would be interesting to hear more about how brain cells are impacted as cellular signaling in these pathways alter cell development. AND how does how normal and supplement nutrition help or hinder these pathways as they do what they do.

Is there a reason why you do not use a fitness/health tracker?

I was wondering the reason I never see you wear any fitness or health trackers such as Apple/Garmin/Whoop devices. Do you not trust the data or the anxiety they might give you?

Does "grounding" have real benefits? If so, what about grounding mats vs. earth in the outdoors (barefoot, of course)?

I'd love to hear what you have to say about grounding -- if there's anything to it and if a commercially available grounding mat truly mimics the earth.
