I hear you, but genetic change at the level of these diseases and traits can take on the order of hundreds of thousands of years or more to accumulate into meaningful trends. Social society is a part of that process, in the way it might be for other social animals. If social dynamics tend to result in communities harboring vulnerable individuals, then there is probably some selective advantage to that behavior, not the other way around.
This is a common misconception. These traits are not likely due to modern medicine (which is very, very new compared to the scale of human evolution). The environment plays a big role, but there is always a distribution of traits in a normal population, some good, some bad. Not to mention that what we might be self-selecting for must change very rapidly as civilizations rise and fall, preferences shift like the winds, and ethics rapidly evolve. I think this misconception can be dangerous, because of what you mentioned. Eugenics.
I decided to give it a try over the weekend on a road trip, through the apps Organic Maps and Go Map!! I really liked Go Map!! except that it crashes occasionally, and won’t restart until your reinstall it :( loosing all the GPS tracks and unsubmitted data :(( If it was more stable, I’d recommend it to everyone.
Use KeePass!! It’s an opensource, offline if you’d like, password manager that doesn’t trust any third party servers to manage your sensitive information. https://keepass.info/
It does. And Firefox is my default browser app.
