Ben Stiller's worst nightmare - dating via social media

Actor Ben Stiller says that it would be "horrible" to be single at his age.

The 48-year-old, who plays Walter Mitty in his new film "The Secret Life of Walter Mitty", is married to actress Christine Taylor. He says struggling to connect with the world of romance through online dating like his character in the film would be his worst nightmare, reports femalefirst.co.uk.

"It would be challenging for me to be in that situation, being single in your 40s and facing that responsibility - to have to communicate via social media. You have to put yourself out there; it's expected. 'What's your Facebook, your Twitter?' British newspaper Metro quoted him as saying.

"But what if you are like Walter and are not good at it? I am not good at it. It would be horrible to be single at this age and have to put your profile up. I have no idea how to sell myself and I really don't want to," he added.
