For the first time in American history, "children born in certain parts of the United States of America can expect to live shorter lives that their parents' generation," according to a report prepared for Sen. Bernie Sanders. The report, and other research, will be released on Tuesday at a hearing of the Primary Health and Aging Subcommittee, which Sanders chairs.  The hearing will be live-streamed beginning at 10 a.m. Tuesday. You can watch it here and on the Senate health committee website. For a preview, read the report.
