"For me, happiness is not having to be somewhere at a certain time..." That somewhat describes me. I have many interests. I pursue one until my interest is drawn to something else. I excel at inventing and starting projects. I don't insist on finishing them. It's the process that entertains me.
Health problems can interfere greatly. If not for the virus, my wife and I would be taking car trips to Arizona or Idaho.
I can sympathize with the health issues. I've had 4 different abdominal surgeries between 2010 and 2015, and I'm heading to the surgeon's again in two weeks to see what's going on in my gut. He told me two years ago I had another good sized hernia in my lower abdomen, but it wasn't bothering me, so I decided not to do anything about it. Now I'm having discomfort in another area, and I want to make sure it isn't anything serious. I can climb three flights of stairs carrying a bag with two six packs of soda slung over my shoulder, and it doesn't bother me, but if I move quick, or get up a certain way, it lets itself be known. Getting old sucks. It seems like every day I wake up with another ache or pain that wasn't there the day before.
I hope you and your wife will be able to hop in your car and do some traveling. I drove from New York State to my youngest son's in Indiana in early August. Stayed overnight in a hotel in Ohio on the way out and back, and ate out at restaurants there. Had no problems. Of course I hated having to wear a mask, but the restaurants I ate at didn't even say anything if people walked in without them.
