Untreated ADHD is the main thing keeping me out of the workforce. Thank our government's restrictive policies around the diagnosis and medication for that. But its not like I'm sitting around enjoying the high life. My spending is basically poverty level. Most people would find it completely inadequate. No wife/kids so that helps.
I'm not _completely_ unemployed, I have a programming contract but I barely bill any hours. Also 10-15% of my time is spent providing what I call "social support" for my aging parents.
