  • I disagree. While most things are best measured per capita dividing it this way is kind of silly. China uses MUCH less energy per person than the US. As does every country. So it’s not really a useful comparison. It’s better to look at the percentage of total energy usage by country that is renewables. Dividing it by person ignores the fact that the average USian just uses an absolute metric fuckton of energy day to day. Like many times the global average. For China specifically, the average US person uses 2.5-3x more energy than the average Chinese person.






  • And little fun fact the US might have spent BILLIONS building missile defences in Israel but they haven’t built a single missile defence system along the gulf coast or anywhere else in the continental united states. The only thing they have is ICBM defence they do not have the missile defences the gulf states, US bases, or Israel have. If Cuba launched drones or missiles then the only way they can defend is to sit destroyers in the sea and try to use those to intercept them. Or use fighters. Which are not very good at doing that.




  • There is a difference between what I was talking about and what these studies are talking about. They are studying the actual effects on users. Because electric toothbrushes are able to clean teeth more quickly and with less effort people generally have better outcomes with them overall. What I was pointing out is that this is not the same thing as a “better brush”. Clean teeth are clean teeth. Doesn’t matter how you get there, and a manual brush is perfectly capable of cleaning your teeth. It’s just that your supposed to actually brush for 2 whole minutes and use the proper technique which most people don’t do. An electric brush compensates for this which is what the improvements seen in those studies is showing. This is what I meant by the common misconception. People see that generally electric toothbrushes cause better outcomes and assume the overall ability to clean must be better, but if used properly a manual toothbrush gets the job done too.


  • It’s actually a common misconception that vibrating toothbrushes clean your mouth better than manual ones. Just takes a bit of extra effort and time to do it manually. Brushing twice daily for two minutes, covering all tooth surfaces with gentle, short strokes or a proper scrub/polish motion, and reaching along the gumline, is what matters most. Most people fall short on time and technique so that’s why dentists will reccomend the electric ones. They do make it easier to get the job done, but there’s nothing inherently worse about a manual brush.
