I'm definitely unable to work, my job was managing scores of huge databases and doing loads of data analysis and network troubleshooting. My memory and focus was going and I was really messing up, I knew a pink slip was imminent. Your comment on "coming up with software designs" is accurate and true, but somehow it doesn't sound solid to me in the way a lifting restriction would. I think of restrictions as things that would be DANGEROUS to do. And how can software design be dangerous?
