Here's the oddest thing I've experienced in the last year...assuming it's age, hopefully it's not a tumor.
For the first 30 years of driving a car, I would park to go into a store, and walk out and head in the general direction of my car. I'm not saying I never occasionally took a minute or two to find my car, but I always went at the very least to the general area, WITHOUT ever thinking about it. It never rose above my subconscious...never once (other than a sporting event or something) did I ever have to mentally register where I parked, or think which way to head when I left the store. I just did it like breathing, even if it was hours since I'd parked, like at the movies or something.
Now, in the last year, about half the time I walk out of a store, and literally don't have the foggiest idea of what direction to walk. It's disorienting for that previously automatic information to be missing...to have to intentionally call it up and have it not be there. I am going to have to start taking a mental note of where I park now, which is hard to remember after decades of not having to do so.
I don't love the extra ear hair or anything, but that's the most frustrating thing I've experienced.
