Actress Julia Roberts feels she has taken a `big risk` by not going under the knife to fight the ageing marks.

"By Hollywood standards, I guess I've already taken a big risk in not having had a face-lift,` the 47-year-old actress told You magazine, reports contactmusic.com.

Roberts, who married Danny Moder in 2002, has three children and she is loving her life. She credits her healthy and wholesome lifestyle for keeping her happy and worry-free as she gets older.

"There's a lightness to my life now -- an airy quality of not taking things too seriously. That's happiness.

"It's about non-grasping, non-hoarding, cleaning out your closet, dusting out your mind and letting go of the things that weigh you down mentally and emotionally," she said.
