PHILADELPHIA (AP) _ Mike Wallace says he doesn't blame Barbara Walters for her decision to step down from ABC's ``20/20,'' the newsmagazine she's called home since 1979.

``She's of a certain age now,'' the 85-year-old Wallace told The Philadelphia Inquirer in Tuesday's editions. ``She doesn't want to keep getting on planes. She's very wise to do what she's doing.''

Wallace has cut his workload on CBS' ``60 Minutes'' to about eight stories a year. Walters, 72, said she will keep doing five or six specials a year for ABC News, including her annual pre-Oscar show, and continue to appear on ``The View,'' the daytime talk show she created.

``Because there are so many shows on and because I've been so hands-on _ I've had a piece on almost every single week _ I don't know how to cut back on that,'' Walters said Monday. ``You really can't.''
