In regards to your first couple questions - You don’t always need continuous data to understand your own biology.
Pen + paper works because you’re tracking the inputs that actually move the needle—sleep, sunlight, nutrition, movement, mood, stress, etc. Those patterns tell you far more than a device buzzing on your wrist.
In regards to the EMF question - When Robert O. Becker went on 60 Minutes in 1977 warning that non-native EMFs might have biological effects, his Navy-funded lab was quietly defunded. The research wasn’t disproven — it was never allowed to continue.
So when people say “there’s no evidence EMFs cause harm,” notice how convenient that half-truth is for industries built on nonstop wireless tech. Absence of evidence is not evidence of absence.
Billions have flowed into expanding Big Tech and Big Electric — not into studying long-term biological safety. No shocker there.
And honestly… we’re all on Nostr for a reason, right?
