I'll second including discussion of different areas in which humans are more and less risk-averse.

I work in a heavily risk-averse field, and I find that hesitation due to fear of failure has become ingrained in me. I used to be much more spontaneous. I'm still willing to sound like an idiot, which is good, but it's a lot harder for me to propose actions that could result in loss or damage to expensive public property, even if I really think the probability is heavily in favor of learning without loss or damage.
