Absolutely yes things have gotten worse as I'd gotten older. I don't tend to bump into things unless the room is disorganised, but tripping over things, having difficulty going down stairs especially when its dark, tripping over my own feet, tripping over nothing, walking down steep hills, staggering when the bus jerks to a stop and ending up with bruises and tripping over nothing; yep, do all of those.
I can't hike anymore; had trouble even at my peak in my twenties; far too stressful and most people have no sympathy. I did manage to go hiking in the Grampions last year, but that's because my two cousins are empathic people, even though they are agile.
I can't deal with snow. I swear, every time it snows I almost go into cardiac arrest from all the stress. I catch a taxi home, but even going down the stairs (which had been cleared) to get to the taxi is peril. Since I broke my arm on black ice, it's been worse. A friend said the loss of confidence is inevitable cos of the trauma.
Pilates has helped. Last year, I had a terrible limp. My pilates instructor said it was age (in my 40s), but I'm sure being on the spectrum and being tense all the time hasn't helped.
