Ideally I would work from home so that I could rest when necessary and be near the bathroom. Most companies require working from an onsite location first before being promoted to a work from home type of position. My last employer was like this. The work from home jobs were highly sought after and many of them required being on the road extensively at times, as well.

I've wracked my brain trying to think of small business ideas that I could do from home that would earn a decent living, and that wouldn't require a lot of physical strength or energy.
