Have ADD, only officially 'labelled' in 2000. However, like many 'sufferers', I have a high IQ, and had learnt to disguise it over the years, along with my lysdexia
My proclivity for the amassment of huge piles of 'stuff' has absolutely nothing to do with ADD/OCD or any other disorder - apart from disorder itself; it is pure and unadulterated laziness. I do not collect objects in the sense of an aim in itself. I have, over many decades, learned to live with this affliction and simply accept it as 'me'. I do sympathise with those who have such leanings - that's the compulsive side of a personality - as I have had something similar for many, many years now but which is not at all related to the collection/arrangement side of things ... no, I'm not going into it here.
[Riff] You are correct, to a point, but is it just that you are afeared that the other parties to a conversation may be ignorant of the meaning of certain words and, therefore, you 'lower' your language to the level that you surmise is acceptable?
I did a test online today for those. Luckily, I appeared to score low on pretty much every disorder, although I tested as "moderate" for Schizotypal, Obsessive-Compulsive, and Paranoid and "High" for Histrionic and Avoidant. Happily, I know what none of these things mean, with the exception of obsessive-compulsive disorder (ocd) which anyone who knows me knows is rubbish (coathangers, anyone?) I'll go with Dujon. I'm just lazy.
Locospotting if you don't mind. As a 12-yr-old I was a locospotter, but it was all steam in those days, and also regarded as quite normal. We all indulged in serious trespass in pursuit of engine numbers. But these days if I see a 30-yr old in an anorak, yes!, at the end of a platform noting the numbers then there's something seriously wrong. It's not OCD; just sad. How can anyone be interested in a sodding diesel? No charisma. And they don't talk.
