Chicken pox, etc. were around for years and had some nasty long term side effects besides death. It didn't bring life to a standstill. Covid-19 is going to be around for 2-3 years before most of the world's population is inoculated (minimum).
Remember, the scare about killer bees from south america in south u.s. Now its Japanese wasps on the west coast. Bottom line is you learn and adapt; that's how the human race has made it this far in this world. The 2 month training camp for Covid-19 is ending and people are moving forward, thank God! You learn, adapt and move forward. I won't be taking any cruises until mid-2021 earliest. I'll wear a mask in large crowds and stores with more than 10 people in it. Football season with masks and waterless hand wash stations in stadiums this year. Since its 2020 and not 1918 somebody will design a mask that can be opened up to slip a sip from a bottle (glass outside during tailgating and plastic in the stadium).
What's the odds for somebody under 65 having major problems with Covid-19 anyway? Probably the same as someone having a run in with police for drinking too much after a game...
