I have no personal fear of the new strains, but I keep my vaccines up to date, and I do mask. Why? My 87 year old mother in law is frail, and I have known too many good people in her situation that died from the virus. I've always gotten along fine with people much older than me, but through the worst of the pandemic, I lost a few of those friends before they should have had to die. Most people in her family seem to live well into their nineties, and I'd like her to have a shot at that.
People phrase it as a question of fear, but to me that's just politics talking. In my situation, a mask in crowded contexts is annoying common sense. I occasionally get comments and cracks from the flat earth gallery (according to a weird man in the local Mall, I'm apparently the only bald sheep on the planet) but most people just mask or not, and don't bother each other. If you go into a large store, you'll probably see about 40% masked, and no one bothers anyone else about it either way.
My life is back to normal, pre-Covid, except I retired to take care of a family member with cancer in the middle of it all. She's doing fine now, and life goes on. I keep a supply of fresh masks and use them in what I see as risky situations. The ever mutating virus is with us now, in all its evolutions, and we can only try to do our best by those around us.
