ADHD is a meaningless psychiatric diagnostic [1] of symptoms, not cause. The diagnosis is used to put millions of people in America on maintenance doses of addictive psychotropic drugs. Routine use of amphetamines almost always causes people's mental conditions to worsen, eventually.
Tonight one of my regular taxi passengers txt-messaged to ask if I was working. I was exhausted one night, when he was going home from the gay strip club, so I stopped at the coffee shop that was half-way between the strip club and his mother's house. I was like, "so... what's your story?"
When the passenger was in high school, he was diagnosed with ADHD. The doctor got him addicted to Ritalin, or one of the other legal prescription amphetamines. At first the amphetamine was great, but then side effects developed. Then he developed some legal troubles, which led to living in a halfway house, with hostile housemates...
Anyways... He's a bit of a mess... probably early or mid-30's... his mother pays his taxi fares. He had a job at the baseball stadium, but then he got fired. Last I saw him, he was collecting unemployment insurance.
People... people are interesting. This passenger didn't use "ridesharing" because he can't manage his money well enough, iirc.
