Yes, much of the world supports them now - specifically in North America; Amber alerts originating in any of the 3 countries with flight-risk can change CA-US, US-MX border protocols https://en.wikipedia.org/wiki/Amber_alert
"The Challenge" ("Vyzov" in Russian), is a 2023 space drama film shot on the International Space Station. It's the first feature-length film with actors shot in space. According to its IMDB page, the movie follows a surgeon who flies to the ISS to save a cosmonaut who suffers a heart attack.
On the topic of toothpaste, I developed a reaction to SLS - Sodium Laurel Sulfate. That's when I switched to Sensodyne, because it doesn't contain SLS. For awhile, Sensodyne was a problem and I began using Baking Soda. Then returned to Sensodyne after a few weeks.
Before this sensitivity, someone asked if I whitened my teeth because they were whiter. Using an electric toothbrush changed the color of my teeth for the better.
A Water-Pik helps the gums rejuvenate as does flossing.
SLS - as well as being the thing that makes orange juice taste rank after you've brushed your teeth - also gives me huge mouth ulcers (canker sores). Sensodyne has been amazing for this.
Someone also mentioned a water pik is great for tonsililiths too.
For each cell, it can be one of empty, type 1, or type 2. In the matrix you specify what the next step is given 0 - 7 type 1 neighbors and 0 - 7 type 2 neighbors, the 'classic' rules would be (only one type):
Empty Type 1 Type 2
T 7 | E . 7 | E . 7 | .
y 6 | E . 6 | E . 6 | . .
p 5 | E . . 5 | E . . 5 | . . .
e 4 | E . . . 4 | 1 . . . 4 | . . . .
3 | 1 . . . . 3 | 1 . . . . 3 | . . . . .
1 2 | E . . . . . 2 | E . . . . . 2 | . . . . . .
1 | E . . . . . . 1 | E . . . . . . 1 | . . . . . . .
0 | E . . . . . . . 0 | E . . . . . . . 0 | . . . . . . . .

0 1 2 3 4 5 6 7 0 1 2 3 4 5 6 7 0 1 2 3 4 5 6 7
Type 2
The way you "read" it is left to right:
If the cell is empty, matrix 1 applies. If it has 3 Type 1 neighbors exactly, then in the next iteration it will have a Type 1 value. If it has more than 3 Type 1 neighbors or fewer than 3 Type 1 neighbors it will be Empty in the next iteration.
If the cell is type 1 then matrix 2 applies. If it has 3 or 4 type 1 neighbors it stays type 1, if it has fewer than 3 or more than 4 neighbors it becomes empty on the next iteration.
There are a number of ways to expand this, you can create two 'co-species' where they follow the original rules for their species and ignore the other except for conflict (3 neighbors of type 1 and 3 neighbors of type 2). You can create 'evolving' species where an over population of type 1 neighbors generates a type 2 cell which behaves using existing rules. Etc.
You change the rules by placing E, 1, or 2 in each matrix spot. Any spot that has more than a total of 7 neighbors is invalid (so the top right diagonal half of each matrix).
