People fall into two camps about genetic testing — some people just don't want to know and others are keen to, says Hsien-Hsien Lei at Eye on DNA. She points out a story in the Middletown Journal (Ohio) about a cancer patient who has undergone genetic testing and her family members who are apprehensive about doing it. Another story, Lei points out is that NIH Director Francis Collins was motivated to lose about 20 pounds after being genotyped and finding an unexpected risk for type II diabetes. As for herself, Lei says, "I should want to know but I don't."
