I can’t remember if it was Russell Barkley, or Nick Hallowell, that compared the ADHD brain to a Ferrari, but either way, I’m pretty sure your brain works just as well as your joints. A little too well, and it takes a little more control to keep them from going too far.
That’s my entirely uninformed opinion, of course. But I’m glad that the peace resonated with you. I have done a lot of performance art, and worked with people with hypermobile joints, and have marveled at what they have been able to do and also heard them complain about the side effects , so I definitely sympathize.
