Demi Moore thinks laughter is the key to stay young

“I pretty much think of myself as like still being about five – maybe that’s why my Twitter picture is of me at five,” the Mirror quoted Moore as saying at a press conference for her new movie ‘The Joneses’.

“I don’t know if there is any particular secret [to staying youthful. I think that laughter and smiling are one of the best antidotes to ageing that you could possibly have,” she added.

Moore is married to 32-year-old Ashton Kutcher and has three daughters,Rumer,21,Scout,18,and Tallulah,16,from her ex Bruce Willis.
