Ahead of his 100th birthday, Hollywood Legend Dick Van Dyke says giving up smoking and drinking alcohol has helped him to live so long. While hosting a fundraising event at his Malibu home, he spoke with his 74-year-old son about giving up the vices. ‘If I liked something, I was going to overdo it,’ he admitted, before explaining how that led to a life-changing wake-up call. The Hollywood legend turns 100 on December 13th. #birthday #hollywood #star #100
