How much exercise will maximize longevity? (2020, sebastianrushworth.com)


So what conclusions can we draw?

First of all, I want to reiterate again that all these studies were observational, so most likely, the longevity benefit from exercise is smaller than was found in these studies. As mentioned above, the people who don’t move at all are to a large extent people who are really sick to begin with, and it’s often their underlying illness that is killing them, not their lack of exercise. As a doctor, pretty much the only people I see who are completely bed-bound are people with severe diseases who are in the last few months or years of their lives regardless of what they do. And healthy habits travel together, so people who engage in exercise generally also drink less alcohol, smoke less, and eat more healthily.

At the same time, I think it is reasonable to assume that there is some significant benefit to exercise, considering all the studies that show it improves cognition, balance, bone density and so on – things that should reasonably be expected to promote longevity.

Secondly, yes, the 30 minutes per day of and 10,000 steps per day recommendations do seem pretty reasonable in light of these studies. If you do 30 minutes of moderate intensity exercise (of which walking to and from the bus station or tube definitely counts) then you are reaping at least 90% of the longevity inducing benefits of exercise.

If you do 10,000 steps a day then you are doing plenty. 10,000 steps is roughly equivalent to 5 miles (8 kilometers), which is about an hour and a half of walking at normal speed, or two hours at slow speed. In fact, you could walk half that and you would still be getting more than 90% of the longevity inducing benefits of exercise. So, even if you’re only getting 5,000 steps a day, don’t worry. You’re still getting 90% of the longevity benefits of exercise.

If you want to squeeze every last drop of longevity possible out of exercise, then you should be aiming for 35 METs per week, equivalent to 12-13 hours of walking at a moderate pace, or 6 hours of cycling, or 3-4 hours of running.

Well I couldn't stand it 'unfinished' so went ahead and 'completed' it. First pass. I need to go back and correct, fix, adjust a few things...maybe another few hours...we'll see. Then on to something else. I don't think I'm going to do this one again on different paper...but who knows...

Farmers’ Handbook – UPDATED (2020, permaculturenews.org)

Although the information is specifically tailored for Himalayan conditions, almost everyone will find some useful ideas and information in this comprehensive work. The whole handbook is 50 chapters in 5 volumes – a total of 792 pages, including 170 pages of colour photos and illustrations.
The Farmers' Handbook is great! :-) I wish they published it under CC-by-sa or GNU FDL in editable format, rather than PDFs.

Al valorar sólo cómo discutir, nos hemos olvidado de cómo hablar
Cuando tenía unos diez años de edad, los chicos de mi clase decidieron intentar en masa que las chicas les dieran un puñetazo en el estómago para probar que podían resistirlo. Para aquella a quien le proponían dar el puñetazo no había forma de ganar: si entrabas en el juego y no conseguías doblarles eras una blanda; si te negabas, eras una fracasada.

Al valorar sólo cómo discutir, nos hemos olvidado de cómo hablar


En tanto que adultos, en lugar del “¡Pégame!” nos encontramos hoy seguidos por gente que dice: “¡Debate conmigo!” Lo que pasa a continuación sigue la misma lógica del juego infantil: o entras en ello y acabas en un altercado sin sentido que degenera en encono, o bien, te niegas y te acusan de ser frágil.

Los foros en los que nos encontramos para debatir cuestiones – el Brexit, la inmigración o las “políticas de identidad” – están estructuralmente diseñados para exacerbar, más que para explorar o resolver, las diferencias. Se favorece el conflicto por encima de la conversación, la animosidad por encima de la indagación.

Night Owl or Early Bird

Whether You Are a Night Owl or Early Bird May Affect How Much You Move (2020, nytimes.com)

Early risers did the equivalent of walking 20 to 30 minutes more each day compared to “evening types,” who tend to stay up late.

Night owl. Don't need a test for that.
Adapting to night shift takes one week and I am fully within the rhythm, with changed body rhythms and everything. But when I need to switch back to daytime living after that week ... that does take me several weeks.
A long time ago I earned some money by delivering the newspapers. They arrived at about 3 a.m., so I did not bother going to sleep. When finished I bought some fresh rolls, read the newspaper and went to bed. Sometimes I got up, had breakfast and went to the club for a concert or our community radio's editorial meeting.

... But the test confirmed this. My score was about 25, if I remember correctly.
Yes, I check it regularly, as I still need to find some cycleable roads.

..Snarky Puppy isn’t exactly a jazz band. It’s not a fusion band, and it’s definitely not a jam band. It’s probably best to take Nate Chinen of the New York Times’ advice, as stated in an online discussion about the group, to “take them for what they are, rather than judge them for what they’re not.”

Plants ignore the most energy-rich part of sunlight because stability matters more than efficiency, according to a new model of photosynthesis.
