Offline: COVID-19 is not a pandemic (09/2020,

But what we have learned so far tells us that the story of COVID-19 is not so simple. Two categories of disease are interacting within specific populations—infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and an array of non-communicable diseases (NCDs). These conditions are clustering within social groups according to patterns of inequality deeply embedded in our societies. The aggregation of these diseases on a background of social and economic disparity exacerbates the adverse effects of each separate disease. COVID-19 is not a pandemic. It is a syndemic. The syndemic nature of the threat we face means that a more nuanced approach is needed if we are to protect the health of our communities.

Syndemics are characterised by biological and social interactions between conditions and states, interactions that increase a person's susceptibility to harm or worsen their health outcomes. In the case of COVID-19, attacking NCDs will be a prerequisite for successful containment.

The most important consequence of seeing COVID-19 as a syndemic is to underline its social origins. The vulnerability of older citizens; Black, Asian, and minority ethnic communities; and key workers who are commonly poorly paid with fewer welfare protections points to a truth so far barely acknowledged—namely, that no matter how effective a treatment or protective a vaccine, the pursuit of a purely biomedical solution to COVID-19 will fail. Unless governments devise policies and programmes to reverse profound disparities, our societies will never be truly COVID-19 secure.

Our societies need hope. The economic crisis that is advancing towards us will not be solved by a drug or a vaccine. Nothing less than national revival is needed. Approaching COVID-19 as a syndemic will invite a larger vision, one encompassing education, employment, housing, food, and environment. Viewing COVID-19 only as a pandemic excludes such a broader but necessary prospectus.

Grapefruit Is One of the Weirdest Fruits on the Planet (2020,

From its name, to its hazy origins, to its drug interactions, there’s a lot going on beneath that thick rind.

Wow. @Alimentazione e quello che sta intorno thanks for posting.
Extremely interesting article. And obviously very well researched, too. Giving not only background information to Grapefruits and it's place among the citrus family, but also it's history and ... some interactions with medication that seems to be really important to know.
As of the article grapefruits can pump up a drug's bioavailability to 100%, which is abnormal and can lead to overdosing as prescriptions always taking into account that usually just a fraction of the active agents actually arrive in our system. For some pills etc it's just 10%. And now imagine that after eating grapefruit, that 10% are suddenly 100% ... depending on the drug this can have unwanted and not always positive side effects.
Okay !

How much exercise will maximize longevity? (2020,


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,

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.
