I have a medical POA to make decisions for my care if I'm not able to. As far as a will goes, I think my biggest issue is that neither of my children want to inherit and run the business. I was hoping to keep it in the family, so that's a disappointment. Maybe one of them will have a change of heart down the road.
@Rosebud as far your medical care goes, most states have made it easy and free to work something up. Google your state + advanced health care directives or your state + living will and see what you can find. You'll find lots of templates and forms that are ready to go.
