There IS the HPV vaccine, which is basically a cancer vaccine for one set of cancers.

I use an iPhone at the moment, so I don’t have direct experience with the Android version, but I very much like Yr. It is free, I think open-source (they at least have a github page), gives you a good amount of info (hourly, 3-day, and long-term forecasts, graphs of temperature, pressure, wind, and rain UV index, maybe a few other things), gathers basically no data about users, has no ads, and has a reasonably good UI. It’s maintained by the Norwegian Meteorological Institute, so it probably works better in Norway - but I am in the US and it’s honestly been fine for anything that doesn’t need minute-by-minute updates (per their website it updates every 6 hours outside of Norway).

I’ve made this plenty of times. Whole canned tomatoes are usually better than diced - just break them up a bit by squishing them with a spoon when you put them in the pan. Needs to cook for a good while - 45 minutes out so. And add salt at the end to taste! But a super reliable sauce and requires very little equipment out prep.

Love the modified Julian date. You’ll also find some satellite-based astronomers measuring their observations in kiloseconds (I think Hubble does it in orbits but most of the X-ray satellites use kiloseconds).

Apple music also pays more per stream than most of the other streaming services. Or at least it did the last time I checked.
