Other than wearing a mask everywhere and sanitising groceries my general habits haven't changed all that much.
Which carries over to my hobbies.
They're mostly indoors and entirely solitary ventures, which is tailor made for global viral pandemic times.
I play video games, read, write, cook, can food, fix up my house to make it comfier and safer, do woodworking, hand carve/whittle, garden, hike/camp, forage in my yard, create and sew patches, rug hook, knit/crochet. And the list goes on.
It's kind of nice to have things to do that don't rely heavily on outside sources to function.
