Oh yes, belt loops, sleeves, and sometimes pockets bringing me to an abrupt halt, I'd forgotten about that. So many things I just take for granted and let free from my memory, no wonder I can never explain anything to anyone

Fidgeting, yes, though mine's subtle, so I wouldn't get told off - part of being brought up by an (at the time undiagnosed) Asperger mother, I guess, whose response to stuff I could never predict, and who wanted me to behave like a 'proper little lady' and not the 'ruffian' she often accused me of being.
Regularly smack myself in the face or poke myself in the eye - my other half seems amazed how often it happens, but at least I've only once got him in the 11 years we've been a couple (probably helps that he's in NZ and I'm in the UK, and only get to see him for 3-6 months of the year, lol - keeps him safe). I did manage to stab a friend in the finger with a scalpel at art college, but fortunatley he quickly forgave me, and learnt to keep his distance if I was wielding sharp objects. My other half has banned me from using power tools since I dremmelled the skin between my thumb and forefinger. I am a real danger to myself, lol.
Greenjadedragon, you mentioned nearly taking a header down the stairs - that's one thing I do worry about, in the middle of the night, when I come out of the bathroom and see the steep fall down the stairs, knowing I'm at my unsteadiest at that time of night. Have often thought I need a barrier across the top, but so far the fear of falling has stopped me doing so.
Perhaps I should just wrap myself in the mountain of bubble wrap I've accumulated over the years, padded out with some cotton wool. It's that or put padding on all teh edges of furniture and door frames, and a big crash mat at the bottom of the stairs
