Keeping the vulnerable more protected (we've been very half @ssed about this) and 2. Reasonable precautions (masks, etc.). I didn't really address reasonable precautions for the less vulnerable, so yes agreed there. But lock down? That only makes things worse in the long run. Restaurants, bars, sporting events, theme parks, air travel, etc. should be fair game, just wear a mask when seated in close proximity to another. Not saying we should have kissing booths set up to get it over with, but lock downs like the re-shut down of bars in TX are counter productive at this point. It's a balancing act and we're being way too protective of the less vulnerable and not protective enough of the vulnerable IMHO.

The only way to get around this reality in the near term is with a vaccine and I don't think that will happen before herd immunity. The CDC now says the number of infected in America is about 20M, so we've hit 10% of our "goal".
