Weeks before the official lock down, coworkers were already changing behavior. Going out to dinner less, stocking up on food, buying extra supplies, etc. Not everyone was doing this, but it was not uncommon. This was weeks before the first case hit the area.

I think a lock down of sorts would've happened eventually, no matter what. Once restrictions are relaxed, a large percentage of people are still going to be very, very cautious. I will not board a plane or sit in a movie theater any time soon.
