A patent attorney once told me about one of his clients who started a full body scan business, where anyone could come in and elect to get a scan. Healthy people would come in just for the peace of mind of knowing what's going on in their bodies. He ended up going out of business because the scans found problems 100% of the time! Apparently there are always bad things to find and it does not always pay to point them out. I found this very interesting. . . .
