revision sic : blue light, vitamin D

So my kimchi batch since the top of October has had a too-high ratio of Ca to Mg. Compounded issue with my bumpy calcitriol supplementation. This correlated down to muscle tightness during fatigued longer runs. I think I have fixed the calibration.

Meanwhile a friend mentioned winter sickness, so I did some revision on D and the blue light pathway.

Nerdy details:

- bulb products: 3000K has the least blue light, 6500K has the most

- you want more blue to wake up, and less blue to get sleepy

- blue triggers signaling that has nothing to do with vision: one signal even has to route out of then back into the brain to the pineal, which evolved from an ancestral first eye that is now buried :p ...

- vitamin D is a critical co-factor in downstream effects

Also, it turns out that the body reacts to hypomagnesemia by throttling vitamin D activation, and thus calcium uptake and retention

Also most people have no sense of scale. 

10^(3, 6, 9, 12) USD is the right scale. 

The folks in the 4s going to 7s are just distracted

I thought of an old friend from childhood, who used to tell me of their run club outings in the 2010s. They were the sort of person who doesn't verbally signal very well, when they want to be possessed, or when they want to be left alone. After a lot of silly guesswork, I took it as a lesson not to bother myself so much with less-verbal people. One cannot always attend to everyone's disabilities. Sweat lost in rain. Deep thrusts and almost coming together. I love my friend regardless. Time.
