Had difficulty keeping up with young 'SS' co-stars: Will Smith

Actor Will Smith says he was so exhausted from partying with the younger stars of "Suicide Squad" that he had to take regular naps.
The 47-year-old actor, who plays antihero Deadshot in the DC Comics blockbuster, has admitted he required plenty of shut-eye after partying with his castmates including Cara Delevingne, 23, and Margot Robbie, 26, reported Female First.
Speaking at the European premiere of the movie at London's Odeon Leicester Square, he said, "I'm 47. Do not hang out with 20-year-olds. Do not do it. It ruins every aspect of your 40-year-old life when you try to hang out with 20-year-olds.

"I had about six weeks on set when I was like: 'I can be 20, this is fun'. But from tattooing, to working 14-hour days and then hanging out for four hours, and parties on set...I need a nap.
