I don't really see this as a matter of being "brave." There is no element of self-sacrifice or helping others in the face of danger here. Our
bodies evolved over millions of years and added mechanisms so that we wouldn't do stupid stuff to get ourselves killed. So, for example, we have an
aversion to allowing anything near our eyes because being blind is not a survival characteristic. Just because we blink doesn't make us cowards; it
means we're smart enough to protect our eyes. Those who did not also did not survive to procreate.
It's the same thing with height. Generally speaking, it's very dangerous. This scenario is, indeed, "safe," but intentionally tricks our bodies
into a reaction. From strictly an evolutionary standpoint, you're not "brave" if you allow this to be done to yourself; you're stupid and a
candidate for the Darwin Award. Not allowing this to happen increases your chance of survival and proves you're smarter than those "brave" people
who allow it to happen.
"He was a really brave guy" is little comfort for someone who falls off a cliff and dies. Yes, this is artificial, but you're still basically just
playing with yourself.
