Hoffman wants to celebrate son's 50th birthday

Two-time Oscar winner Dustin Hoffman wants to live up to 100 years so that he can celebrate his youngest son's 50th birthday.

According to contactmusic.com, Hoffman has promised all his children that he will celebrate their 50th birthday. He said: "I have a pact with my kids. My youngest is 21 and I said, 'I want to be there for your 50th birthday', which means I have to be 100."

He added: "I'm not retiring. I'm against the concept. You retire from a job you don't like, but you never retire from your work."
