I've been under the impression that biggest risk of long term use of nitrous is that it causes b12 deficiency which is really bad for your nervous system. Wikipedia also mentions that NMDA receptor antagonist in general are neurotoxic and studies in mice suggest that nitrous has this neurotoxicity.
Yes, Einstein's theory of relativity was a change from Newtonian physics but it's a fairly minor correction for most practical purposes and Newtonian physics is still important to know and understand.
So yeah, our understanding of physics will likely change but it'll only matter in more and more extreme edge cases and will likely build on our current understanding. Maybe it'll result in us finally having fusion reactor, room temperature super conductors, or quantum computers but you're still going to get a roughly parabolic arc when you throw a ball through the air.
Also, many diseases don't effect you until after you're past reproductive age. Evolution doesn't care if you get Alzheimer's at 70 but it still has a fairly large burden on our modern day society.
Sickle cell is particularly interesting because the gene that causes it makes the carriers less susceptible to malaria. So there actually was an evolutionary pressure for people in areas with high levels of malaria to have it (which is why it's so common among African Americans). Apparently it's better to die of sickle cell at 40 after you've had kids then die of malaria when your 10.
Almost everyone has some sort of gene that isn't great. They might have a family history of Alzheimer's, maybe a family history or some sort of cancer, or bipolar disorder, or any other of 100 different serious illnesses. Humans would go extinct if we only allowed those with perfect genes to reproduce.
Oh, and with sickle cell, you're going to be in particularly hot water with suggestions like that given the fact it's mostly African Americans who have the gene.
They didn't say sending kids to private school was a way to actively defund public education just that wealthy parents do both which is true. What's your motivation to vote and support politicians that advocate for better funded public schools when it doesn't effect your kids but raises your taxes?
1. Historically women were largely responsible for community building. As they joined the workforce, they had less time to community build and so there became less community.
2. Technology allowing home entertainment. People can now stream movies instead of going to theaters. Play computer games instead of go to arcades. Check Facebook instead of call friends to catch up. Use a Keurig for convenient coffee instead of go to a cafe.
