HOW TO REDUCE YOUR COFFEE INTAKE FOR A BETTER LIFE

STEP 1: NO

☕️☕️☕️☕️☕️
If anyone's wondering, while there are few/no health benefits directly attributable to drinking coffee, there is also consistent evidence that even quite high intakes are unlikely to be harmful to your health
(Obviously this is not a blanket endorsement, if your doctor tells you to drink less coffee you probably should. If your naturopath tells you to drink less coffee, on the other hand, you should stop seeing a naturopath)
I have now written a piece explaining this with references and science link.medium.com/9cHS0xuEmhb

The vast outrage over the "unfairness" of a transgender athlete competing at the Olympics makes very little sense when you consider that;

a) she is ranked 4th
b) she is the first trans athlete to compete at the Olympics EVER
"But she has a biologically male body!"

Try defining a "male" body in a way that doesn't exclude a large proportion of elite female athletes. The IOC has been trying to do this for decades and it's VERY HARD
The fact is that most elite athletes have biological advantages (how many 5'2" people play basketball professionally?). It's up to us to decide what is "unfair"

This new systematic review/meta-analysis of ivermectin for COVID-19 has come out, and everyone's asking me to review it

My take - decent study, but the devil's in the details 1/n
2/n The study is here. Because it's about ivermectin, and people are super weird about that specific drug, everyone's going wild with an Altmetric of 8,641 in the week since publication journals.lww.com/americantherap…
3/n I should say that my position on ivermectin previously has been that there is some interesting evidence but that most of the studies are low quality so it's hard to say much (even the one or two high-quality studies aren't very conclusive)

Occasionally people ask how to argue well on the internet, so I'd like to introduce you to the two simple rules for productive internet conversations:

1. Always reply calmly
2. Never assume ill intent
Number 1 is first because it is the most important - DO NOT REPLY ANGRILY

Take a moment

Take a breath

THEN reply
If this takes an hour, a day, a week - so be it. When you reply angrily, you derail the conversation and it becomes a waste of time

A useful point to show why vaccines are so important - even though this is WELL below herd immunity rates, the vaccines already done so far in NSW have probably slowed down this outbreak significantly
Let's think this through - @NSWHealth reports 1.9m vaccine doses, which based on previous figures is probably ~1.5m first and .4m second doses

With a population of 8.2m, that's about 20% of the population vaccinated at least once
Let's assume that all of this was Astrazeneca, with an estimated vaccine efficacy (protection against infection) of somewhere around 70%, and think about some different scenarios of the reproductive number (R)

Another day, another viral article being cited as proof that ivermectin can cure COVID-19

The newest example is even more depressing than previous ones somehow 1/n
2/n The paper is here, and mostly it's just a perspective piece in a minor Nature offshoot (Journal of Antibiotics, IF 2.4) written by two members of what I can only describe as a pro-ivermectin advocacy group
nature.com/articles/s4142…
3/n The advocacy group is called Front Line COVID Critical Care Alliance, and has a very flashy website that basically advocates for ivermectin (and vitamin D, melatonin, and mouthwash) as the cure of all COVID ills

Was reminded of this old blog recently - scare stories about red meat and cancer are still all too common

gidmk.medium.com/red-meat-isnt-…
There's a reasonable basis for arguing that at a population level there might be some reduction in cancer rates if people stopped eating PROCESSED red meat
Less strong is the argument that eating non-processed red meat might impact cancer rates - even if there is some reduction, it would be pretty modest at a population level
