Tips I have learned over the years. In priority order.
Buy a sonicare toothbrush. They are supposed to be better than even Oral B because of the sound waves they produce. May seem expensive but far cheaper than almost any dental procedure. Studies have shown that electric toothbrushes clean better than manual.
Brush daily.
If you cannot brush one day at least use a flouride mouthwash.
Do not use water on your toothbrush. Something in water hinders the effectiveness of flouride.
Do not rinse your mouth with water after brushing. Leave that toothpaste on your teeth.
Buy a water pik and use it. They clean better than flossing.
I remember a 3D version of Tetris on an early IBM PC clone. Very early like 8088 or 286 PC. Don't remember the name and it was only wireframe and 1color (amber or greenscreen?) but I was very impressed with it. Seemed ahead of its time.
The appeal of games like this is so odd to me. They're moronic on one hand but viscerally addictive on the other. A very interesting psychological dynamic going on with this whole genre.
Looks like it will be a BROWN Christmas here this year. Which is a grim fucking reminder that we've fucked the planet and it is only going to get worse.
