NEW YORK (AP) _ At 79, ``60 Minutes'' correspondent Mike Wallace is still ticking.

``I love the urgency of what we do,'' Wallace says in the Dec. 1 People magazine. ``I like the battles that take place, the jousting. You walk into an airport and someone says, 'Hey, there's that guy.' They admire what we do. There are a lot of other newsmagazines out there now, but people still recognize this as the most responsible and the most serious.''

Wallace's workaholic pace includes long hours and about 120 days a year spent traveling.

``He's a force of nature,'' said ''60 Minutes'' producer Don Hewitt, 74.
