Need a plan for sick days

I can not wait until I can retire. I am tired of having to spend all of my free time working and not getting to relax and take it easy even when I am sick.

It seems so glorious, working for yourself. The trouble is that few people realize that it really does mean you have to work even when you don't want to work. I need to come up with a way that I can keep my work running smoothly when I am sick. Maybe write a bunch of stuff that can be posted to the blogs and my websites when I get sick?
