I used to work outside most of the day. The old pleb lab was in a building with a rooftop pool. Before that back in 2018, I'd work in my backyard *all* day, laptop screen glare be damned. 

Sometimes I switch away from things that work to try a new way of being and it's worse and I forget that it's worse.

Sunlight is super underrated as it is our main source of Vitamin D, I had my blood tested months ago and it showed "Vitamin D: 1"... which is concerning, especially for mental health other than bones health etc.

So now I take once a month (max 4 months) 0,266mg of Calcifediol which is the equivalent of 16000 IU, and I can confirm that I feel much better, no placebo.
