@KatyMontgomerie @ElPolloDiabloX @AbigailShrier @chadfelixg Okay, so you haven't read the study in the British Journal of Sports Medicine, you've read a Guardian story about it.

I have now read the study, and I teach critical appraisal as part of my job, so let's dive into it a bit.

12 things you should look out for before buying health insurance

A thread 🧵

It’s a good idea to make sure your health is protected under an insurance policy so that you don’t shell out large sums of money for hospitalization and treatment. But buying an individual health insurance policy can be daunting in itself.

Websites and policy documents can be overwhelming. There’s a lot of loaded terms, there’s a whole bunch of things that your policy may or may not cover. It’s important to know and understand the details though, so you’re not surprised later.

In this thread, we'll talk about the things you absolutely need to watch out for when buying an individual health insurance policy for yourself or your family members :)

If you take an individual health insurance policy and the insurance company offers to pay up to ₹15 lakhs during the year whenever you’re diagnosed with a disease or meet an accident, that amount is the 'sum insured'.

Let’s talk about ORGANIC.

Robert Paarlberg’s new book on the food system is out today, and here’s an excerpt.

He’s not a fan of organic, and he makes some good points but misses others.

Here we go.

Organic's biggest shortcoming is that you need more land to grow the same amount of food.

The yield penalty happens in almost every crop, in almost every study.

The gap could narrow with more research/varieties, but it won’t go away.

This has big, bad climate implications.

The second issue I have with organic, which Paarlberg shares, is that its basic criterion is naturalness.

Natural doesn’t mean safe, or even safer. A farming standard based on it forces farmers to sometimes use more dangerous, less effective tools.

On human health, there’s scant evidence that pesticide residues on conventional produce are harmful to consumers (though it’s possible farmworkers could be at risk).

What I don’t want is for folks who can’t afford organic to worry about feeding their kids conventional produce.

On the plus side, Paarlberg acknowledges that the organic standard has some real advantages for animal welfare.

This is why I buy organic animal products.

Many in the organic world would like more regs ensuring animals have decent lives.

The importance of T-cell immunity!
A recent study has found that after one dose of Pfizer’s vaccine, patients had a strong T-cell response, and a boosted antibody response after their second dose. This is good news for many reasons so let’s read up.

This study found that people’s antibodies were moderately effective against the original strain after their first dose of Pfizer’s vaccine, less effective against the B.1.1.7 variant, and were unable to neutralize the B.1.351 variant. Read what I said, that’s only after ONE dose.

However, they had strong T-cell responses against ALL known variants after the first dose. So why is this important? To recap, T-cells stimulate B-cells to make antibodies. Antibodies are just your first line of defense which is what is initiated when you get a vaccine.

It’s our T-cells that are responsible for long-term immunity. When antibodies diminish after your initial inoculation, your T-cells-will tell your B-cells it’s time to produce more antibodies. As long as your T-cells still recognize this virus and inform your B-cells they need

to produce antibodies, the vaccine is still doing its job. Your antibodies will get built up over and over again. Just FYI your TCRs and your BCRs target different parts of the Coronavirus’ spike protein. Antibodies can prevent infection, your T cell-responses ensure that those
