We can not leave them out," write doctor Donna Zulman and psychologist Keith Humphreys, working at Stanford University School of Medicine in California, and the health care system for veterans . Extrapolating the results of young people to older is risky, because biology is moving with age. Moreover, "old age is not a reliable proxy for poor health," Humphreys Zulman and support. Researchers can even exclude voluntary test if they have certain conditions, but health "not only on their age."
