I'm curious how safe (physically, not career-wise) different trades are for people with ADD.

As a software developer, I get by with a combination of Adderall / Vyvance, software tests, and the freedom to take a day off if I'm feeling particularly flaky.

But I'd imagine that doesn't work with e.g. industrial / commercial electrical work. Partly because schedules assume you're rarely out sick, and partly because making a mistake can kill you or other people.
