Maybe where you live. Here you have to do a lot more than forgetting your keys. It sounds like you believe ADHD is not a real thing. It is and it is loads more than forgetfulness and loads more than being unable to focus.

Here you have to pass stringent tests to be seen as ADHD. They take several days.

Even though I feel I am blessed with ADD, it does make you different. It makes it easier to get some types of anxiety disorders and in my case I have executive functioning skills of a 7 year old. It does get me in trouble.
