Dick Van Dyke, nearing 100, credits his longevity to simple habits. The 99-year-old star, famous for Mary Poppins, believes avoiding cigarettes and alcohol played a key role in his health. He admitted to smoking and drinking heavily in his younger days but realized he needed to quit to improve his well-being.

Van Dyke shared, “I smoked a lot, probably in my 50s I realized I had an addictive personality. I liked things too much.” He then quit both substances, which he believes helped him stay healthy. In 1972, he checked into hospital for alcoholism but managed to get sober, though quitting smoking was tougher for him.

He told the Real No Really podcast, “It was much worse than the alcohol.” Despite occasional fluctuations in energy, he feels grateful, saying, “I never wake up in a bad mood.” Besides quitting drinking and smoking, Van Dyke attributes his longevity to staying calm and avoiding anger or hate. “I think that’s helped me,” he noted.
