Yeah, what he said!

The point is that he gets tired quickly because of health issues, so he simply can't work 5 days a week, 8 hours a day, every week. But maybe he can work 25 hours one week, 15 the next, or whatever works for him. And if he has an accident that keeps him off his feet for let's say, 2 weeks, it won't be a problem, whereas if he had a normal job, he'd either be fired, lose 2 weeks of his vacation or just fired.
