WTF! I object to anyone talking to or about Don like that. Don is long-term member of this community that many of us look up. Via his book and participation on forums, so many of us have benefited. He deserves more respect that that, even if you happen to have a different opinion on a subject, any subject.
That said as I write this, the numbers in the U.S. are 14,070,404 confirmed cases and 276,670 deaths. I suspect there are more cases than have been confirmed, as some people got the virus and recovered without any testing or confirmation, especially earlier. Now more people are getting tested. So if we double the cases, which I believe is fair and divide deaths by cases, you get .00983 or a hair under 1% and 1% is not almost zero, counting is fun. So I would say Don's analogy of 1 bullet in 100 is spot on , just as Don almost always is with numbers.
Now as discussed, different people are at different and greater risks. I am, just as Don is, so everyone is going to evaluate their own risk and situation differently and take precautions they feel necessary. There should be no "shaming" because of that.
One other thing you have wrong is that only the obese and very old are at risk. There is a whole list of conditions, mine included that place a person at greater risk regardless of age. Some are pretty common things, like diabetes, Asthma, high blood pressure and even something like acid reflux, which many people don't realize effects the lungs, as stomach acid that is suppose to be limited to the stomach makes it's way to and damages, other locations, including the lungs. I am going to say, most people over 40 HAVE one of these underlying conditions, especially with higher cancer survival rates which is good, but the cancer treatments damage and weaken immune systems permanently.
If you are not in a higher risk group, do what you want, but for god sakes, show some humanity for those that aren't as lucky and have a greater concern. One day it may be you in a higher risk group.
