There’s also a bit of a gap when it comes to diet.  More than eight in ten centenarians say they eat balanced meals while only 68% of boomers do.

Still, a lot of boomers will reach 100… 600,000 are expected to be centenarians in 2050.  There are fewer than 75,000 now.

The centenarians and boomers surveyed were also asked to choose a favorite dinner guest from among fourteen famous people including the President, Paul McCartney, Tom Hanks and Julia Roberts.

The top choice for both groups: Betty White.
