I wrote a thread on this before on Twitter.
I had to drag someone out of a house when the dryer caught on fire. The insulation had already started to fill the house with the most acrid stench you can imagine.
They wanted to finish a phone call because they had put 50p in the slot already.

Here's a threaded version of Mike's posts about the 🎯🎯🎯 data viz tool he created to explore this recent research on 4-yr-all-cause-mortality.

A recent scientific paper compared long-term mortality by vaccination status.
I noticed that Table 2 drew a lot of attention, but was actually included in the paper as a static image. So I built a quick dataviz project to explore.

It’s 2026 and one of the first things that has happened is that a major news outlet has announced that it will no longer seek information from experts.
I don’t think this is gonna help with what I think is the most existential threat to our society currently: disinformation.

In 2026 there will be more mass media articles and commentators ridiculing people taking precautions to avoid SARS-CoV-2 infection while simultaneously hundreds of pieces of research will be published further demonstrating the long-term harms of infection.

Flu cases are rising with a strain that makes older people sicker
Flu season is ramping up in the U.S., marked by a new strain that could make vaccines less effective. Covid cases remain down.

After a massive bar fire in Crans-Montana, burn injuries far exceed what the country’s centers can handle. About 50 people were severely burned, and victims are being transferred to hospitals in Germany, France, and Italy.

Hey fiftysomethings & up in Ontario, our young friend is reminding me that we are now in a special club that qualifies for the shingles vaccine. Yes, we have to pay for it (or maybe we have a benefits plan that will) but if you can manage it, get the 💉.

Myth: immunity debt
Truth: immunity theft
Getting Covid over & over does NOT strengthen immune system, it weakens it making fighting off even cold or flu harder. Covid vax does NOT prevent infection, K/N95 mask does if well-fitted & you don’t remove in public for any reason. Advocate for clean air✊
