The way Newton man Fred Matthias sees it, there are two groups of people in the world — those who keep moving and those who just sit around and watch television.

Consider Matthias part of the first group.

Despite being 96 years old, Matthias lives the very definition of an active lifestyle. The Newton attorney bikes or walks several hours a day. He continues to work at his law office several days a week. And he does all sorts of activities to keep his mind sharp, like playing piano, organ and trombone, doing crossword puzzles and following the news.
