Including people who get at asymptomatically, maybe. Of people who get any symptoms, it's 15 - 20%.
And even if you're not in that 15 - 20%, you may still have permanent or long lasting lung and heart damage. Stay inside; your grandparents were asked to go to war for several years, you're just being asked to spend a couple months playing video games.
There are tons of videos on youtube that you can just put on your television and follow along with.
Except that most of the world doesn't live in an American suburb where houses are 100 meters apart. For most of the world, going outside means bumping into somebody.
I agree we should look out for the older generation though. For me, it's my parents (boomers, who fought no wars) I worry about, my grandparents (who fought) have passed already.
