Most states just have a stay home except for essential errands like shopping, healthcare etc. No one has been locked down. I'm 70 and the only change to my schedule of the past few years is takeout from our favorite restaurant that closed for now. Otherwise shopping, Dr appointments, post office and some fast food as usual. Some my age are not party animals and find 'stay at home' kind of a normal status quo. I don't think an enforced lock down of a specific age group would fly.
Lock down is the popular term a lot of places so if you prefer, restrictions on that age group without throwing people out of work.
So, you’re a year older than I am, I know what’s the norm and wearing a mask when I’m out makes perfect sense along with limiting we old fogies to not going to group gatherings but half the people in the area being out of work doesn’t.
Everything I do was already on the essential list but since our tags were due, I went ahead and got Farm tags to make it obvious. Here in MO, they don’t mess with the farmers so having a big F plastered in the center of the tags would be handy if they were to decide to go extreme and have check points. The next county over, Iron County, says in their stay at home order that no one from another county should visit or even pass through Iron but I don’t know if or how they’re enforcing it.
