And that is the heart of the problem...."Good move on there part, as long as they are ready to make sure that they do not spread it to people that are likely to have serious problems". Key words "as long as"

The younger people are very low risk and they as a group are not taking things as seriously as they should because they are young and think subconsciously that there is nothing really to worry about. It's really a maturity issue...thinking about consequences, even unintended or accidental, 2-3 weeks down the road just simply is not on their radar. About anything, much less Covid19. It's "living in the present" mentality, which isn't a necessarily bad thing because living in the past or only dreaming about the future can be problematic too...but too much living in the present moment, only, removes forward thinking and strategic planning and an awareness of connections to others not realized today. It's not just the young, but middle aged people who don't get the accidental spreading to the elderly and compromised people. That mindset fuels behavior that is very self focused, self important, self centered, and self instant gratification oriented.

Bottom line is take precautions that are reasonable to keep yourself and your family/friends healthy as possible...remember that both actions and inactions can have serious consequences to others who are vulnerable. Consideration of others before yourself is a rock solid Biblical message.
