Seems slightly worth remarking that I feel very good today. Why?
Don't really know. Did a really hard run on Monday. A 2/2, 2 minutes of high intensity running then 2 minutes walk, for 4+ miles, then gradually going down to a 1/3 as I got really tired for 6 total miles. I've never done that much intensity for that far and I didn't feel great the next day. Head very slightly hurt. Not sure if it was related. Very slightly hurt with very slight nausea. Like a migraine except just the faint shadow of one, which lasted more than 24 hours.

Reading so many bits of books at once. Trying to read Bleakhouse using the audio function of the kindle. But not working well as the pausing is inconsistent. Sometimes no pause after questions or in the middle of dialogue, making it very confusing. Sometimes no pause at periods, while large pause after commas. Inconsistency is ultimately the problem. Then I glance at the page while driving which is dangerous.

Reading The Runner's Body by Matt Fitzgerald, et al. Which goes with this site:

Some useful stuff in it. Such as....
the dehydration myth. Very good to know as I guess I was worrying a bit much about staying hydrated. A lot of stuff I already know though.
Alcohol has anti-inflammatory properties and lately I've been having a beer with lots of ice in it late in the evening, maybe 3 times a week. Thinking about doing that every night. Beer never tasted so good and I think it's why I feel so good. In the past beer left me feeling too hot. And gave me insomnia. But I think it was somewhat psychosomatic. I thought it wasn't good for me and then imagined bad stuff going on in my body. Now I'm thinking it's good for me and feeling quite good.

I do think that aside from placebo effects, etc it really does help my running. Have started reading a ton of other books which I may or may not get into.

Checked BP at work other day. 107/72 Resting HR goes from 50 to 56.
