The Oscar-winning actress says the older she gets, the greater her appreciation for life becomes and admits her children wouldn`t dare complain of being bored with their lives because she would "kill them".
Meryl told AARP The Magazine: "I find the older I get, the more intense my appetite for living and for appreciating life gets.
"I think I was heedless when I was younger. I thought it was endless. But I just lost two really close friends in the last two years, and, man, you realize you`ve got just seconds.
"I mean, my kids wouldn`t dare say they were bored to me. I would kill them! How dare you! You have the gift of life. You`ve got to get out there and eat it!"
The 63-year-old star - who has four grown-up children with sculptor Don Gummer - currently stars opposite Tommy Lee Jones in romantic comedy `Hope Springs` about a middle aged couple who are trying to rekindle the spark in their relationship.
However, Meryl claims it`s not a problem she`s been confronted with personally because of her passion for life and says she has no "prescription" for keeping things fresh in the bedroom.
She mused: "I don`t make any prescription myself... If you`re bored with somebody, it`s because you`re bored with yourself. If you have a problem with somebody, often it`s something in yourself."
