Every time people say "it'd be nice to live in the 50s" or something like that, I always think: "Nope, I'd never trade modern medicine for anything else."

It means that humans developed empathy and the scientific means to help each other avoid natural selection. Intraspecies and interspecies empathy is the cheat code against natural selection. Certain ram species, for example, also were not designed intelligently, so as they age they may grow their horns until they penetrate their skull and kill them. Natural selection is most effective when it culls prior to the life form procreating. However, thanks to the power of empathy, we can abate natural selection by performing oral surgery on humans (ideally in our adolescence for wisdom teeth removal) and by shaving rams’ horns as they age. Ideally, as science develops and empathy spreads, we can come up with more effective and painless means to ensure everybody has a chance to live and be happy.

Medical science is one of the only reasons I'm happy to be alive now and not during other times. Everything else is absolute shit, but our ability to manage and cure disease and the like is amazing.

Watched a documentary on the history of surgery and man, modern medicine is one of the things I'm grateful for.

This ain't evolution. This is science counterevolutionarily keeping our ancestors alive long enough to procreate who should have died. I guess it's evolution in a way since we've evolved to overcome the evolutionary concept of "survival of the fittest" or natural selection.

Evolution didn't make your teeth to grow like this. While people in the past probably had shitty teeth keep in mind that modern diets filled with sugars, processed food and all sort of junk are a cause of teeth problems
