The U.S. Government wants help to create the largest health database ever. Starting May 6, the National Institutes of Health will open enrollment for the All of Us research program, which is an effort to advance individualized health care. Anyone 18 years and older, regardless of health status, is encouraged to sign up. The NIH hopes to recruit 1 million volunteers for the decade-long program; 25,000 people already enlisted in a one-year beta test.
