The `Avatar` actress says she has grown up around weapons and enjoys using them, but always makes sure she`s careful whenever she does.
She said: "Women with guns is happening and it`s exciting. On a personal level, I have respect for weapons and I like using them. I grew up in a family of hunters so I`ve been around guns my whole life, although I would never actually hunt myself. I`ve never taken a life, except maybe an ant or insect here and there - and it still haunts me."
Zoe also revealed how she is "addicted to adrenalin" even though it often leaves her "black and blue".
Talking about her latest assassin movie `Colombiana`, Zoe, 33, told Total Film magazine: "I always go home looking like a map. That`s what my mom tells me because I have black and blue all over the place. But I`m addicted to the adrenalin of being a physical person.
"That said, I`m entering the consciousness of mortality. With `Avatar` I was fine: I`d get hurt, I`d get up, I`d brush it off and keep going. But my body feels like it`s aged 10 years. It can`t reboot as quickly."
