Lucia JacobsGuestElla Hubber[upbeat music] Main challenge is the technical one.
Doing it for 15 years, I do get fear.
Estonian slackliner Jaan Roose performs a daring show 120 meters above the streets of central Seoul.
[groans] I feel fantastic, actually, get to the other side.
It feels great.
Andrada, Michael, how do you feel about this? Are either of you fellow daredevils?
Well, Marnie, some of my friends have called me a daredevil, I guess for being an ice and snow carving competitor.
A bit of the daring aspect of it is using chainsaws and chisels when you're up there in freezing temperatures, so yeah, I guess I'd call myself a little bit of a daredevil.
Well, we know there's a big difference between me and Michael, and we've known for a while that some people seem more willing to take risks than others.
But the question is, can you look at someone's brain and tell whether they are a risk-taker? Or can a brain scan tell whether someone drinks too much or drives too fast or does other risky things?
It was written by researchers at the University of Pennsylvania and the University of Zurich, and they looked at brain scans from almost 13,000 people in the UK, most of them middle-aged and older adults.
And these people also reported things like how much they smoke, how much they drink, or how fast they drive.
And the researchers repeated the entire analysis in a second separate group of 13,000 more.
