Mila Kunis wants to learn brain surgery.
The 'Jupiter Ascending' star - who has four-month-old daughter Wyatt with fiance Ashton Kutcher - enjoys "random" hobbies away when she isn't working or looking after her family but admits she secretly longs to study for a degree in neuroscience.
She said: "My most random hobby is I like gardening. And if I could get a PhD in anything, I would like to be a doctor of Neuroscience... I mean, this is all in a hypothetical world, but that's what I would like to do. Brain-surgery. Yeah!"
While she is keen to study herself, the 31-year-old beauty thinks she has some wisdom she could pass on in the form of a unique class on being an "awesome badass chick".
She said: "I would teach a course... nobody should take any class from me, let's prefix it with that, but if you're forced to take any class from me... I could teach a class on 'How to be an awesome, badass chick who knows how to take apart & put together a gun blindfolded, make a four-course meal, and parallel park the s**t out of a car.' I mean, don't you think? That would be my course."
And the 'Black Swan' star has also harboured ambitions of teaching younger children.
Speaking in a Reddit AMA, she said: "Before I had Wyatt, I would've been a teacher. I would have taught like first grade."
Despite her wide ranging interests, Mila admits at the moment she wants nothing more than to be with her daughter and says the little girl has completely changed everything.
She gushed: "I am proud to be a stay-at-home mom. I have no desire to be in front of the camera. I find her to be the most challenging job I've had. The amount of love that you have, the type of love that you have, changes, the way you look at the world changes... everything has changed, because of her.
"I want an eco-friendly car, I want to compost everything, because I want the world to be better for her. And you have the opportunity to make a really great child for the world. Or a really great human being."
