I've got this thing that I can do that is a bit spooky. I can tell if someone has Parkinson's disease or ankylosing spondylitis, before any symptoms are apparent. I can't do it via TV (not reliably, anyway - I missed Michael J Fox!), but I can in person. Usually I'll write and ask a GP to test, and they'll be really sceptical, and then be amazed when I'm right because of how early I've spotted it. It's nothing I can put a finger on - the idea just comes into my head and won't go away.

Thing is, I've only been able to do this since being a physio, and only after I'd had about 5 years experience. I'm assuming there is something I'm not aware of that gives me that 'gut feeling', but I've 'learned' to notice it outside of a conscious level.

Anyone else do things like this?
