We now know more about who is at risk. Average age of death for people from coronavirus is 80. Average age of people who need medical attention is age 60. We want people who are older, people who have medical conditions, to take steps to protect themselves, including avoiding crowded spaces, including thinking very carefully about whether or not now is the time to get on that cruise ship, whether now is the time to take that long haul flight, for most people you're going to be fine. But if you have medical conditions, or you're older, now is the time to rethink that.
