Dick Van Dyke reveals his secret to reaching 100: avoiding anger and hate. The legendary actor credits his positive attitude for his remarkable longevity.

Dick Van Dyke turns 100 this year, and he says he feels "really good." 

In a recent conversation with People, he credits his attitude for both his age and the fact that he has "no pain, no discomfort."

"I’ve always thought that anger is one thing that eats up a person’s insides – and hate," Van Dyke said, explaining how people often ask what he did right.

He added that he’s "rather lazy" and never felt driven by the kind of resentment that can harden over time.

"Sometimes I have more energy than others – but I never wake up in a bad mood," he told People.

The actor explained that while there were always things and people he didn’t like or approve of, he "never really was able to work up a feeling of hate," and certainly not "a white-heat kind of hate."

He contrasted himself with his father, who was "constantly upset by the state of things in his life," noting to People that his father died at 73.

Van Dyke believes avoiding that emotional pattern is one of the chief things that kept him going.
