The millennials (those 29 or younger) are much more likely to embrace change than either Gen Xers (30-45) or baby boomers (46-64). That's sort of always been in the job description of the younger generation, and it's still true today. They are more likely to have a tattoo (two-fifths, compared with a third among Gen Xers and 15 percent among boomers), have created a profile on a social networking site like Facebook (three-quarters, compared with half and 30 percent) and posted videos of themselves online (a fifth, 6 percent, 2 percent).
