I get a bit upset when people paint all millennials with a broad brush, as my children are in that age group - I did not have children until later in life so am about a decade behind most Boomers. I know many young people on a more personal level than their bosses/co-workers do - and have watched their growing up and how their path has been different than mine. Not better or worse; just different. At least until now. I fear that they may be facing an economic crisis that hasn't existed in almost a century - I hope I am wrong.
I also am a Boomer, and both my husband and I are the youngest in our respective families. We have friends of varied ages because of our many hobbies.
But to assume that all people in the high risk group - even those over 80 - are feeble old people who are just waiting to die is just not true. Perhaps all of the old people you have encountered fit that description, but that would be as wrong as them assuming that all people in their 20s/30s are the same as the young woman in an earlier video.
My brother (78) is still working from home - and has to turn down clients because he has too much work. One BIL (79) just got back from a skiing trip in January with his grandchildren, and he continued to ski black diamond runs just as he has done for decades. His daughter finally convinced him to not teach med students this week, and he had to cancel his yearly trip to operate in 3rd world countries this year. Another BIL(79) is not helping with income taxes this year, nor will he run any Spring marathons, but is still running daily, and is consulting with the Dept of Health as he is an Epidemiologist. He has been doing tele meetings with various groups since his "retirement" a few years ago. Two of our friends still coach - one will be turning 90 this month, and retired from medicine a few years ago. The same with another friend of the same age- he has had to stop working as a volunteer at a free clinic for the duration. My husband is currently out rowing by himself as it fits social distancing guideline - he does not come within 6 feet of anyone. I myself have been sidelined as a sports official because of this, so I am staying at home or in my yard for the duration.
So please be careful when you describe the high risk group as old, feeble, and should be ready to go. I have a few more items on my bucket list, thank you very much!
