 Baby boomers actually feel about 14 years older on average. Of those who say they feel older, 55% say it's because of body pain, 48% say it's because they get tired easily, 31% say it's because they feel less active overall. The poll surveyed 2,000 Americans split evenly by generation with a margin of error of plus or minus 2.2 percentage points. Nick Inelli, WTOP News. There is another confirmed human case of bird flu.
