Downey Jr stressed over turning 50

'I'm 46 now, so the countdown to my half-century has begun,' says Downey Jr.

LONDON: Actor Robert Downey Jr. has started to feel stressed about turning 50.

The 46-year-old actor, whose wife Susan is expecting their first child together, says he is enjoying everything about his life at the moment, reports femalefirst.co.uk.

The "Sherlock Holmes: A Game of Shadows" star, who also has an 18-year-old son Indio, from his previous marriage, said: "Life is good. With a new baby on the way, maybe I ought to think about slowing down a little. But I can't see that happening in the short term."

"It just goes to show that I usually don't know what's good for me in life. But I'm getting better at knowing that stuff. I don't need to rub against the grain nearly as much as I used to."

"I'm 46 now, so the countdown to my half-century has begun. I'd have to be completely deranged not to stress about that," he added.
