I'd like to think of myself more as a logical risk taker. I can do somewhat dangerous things so long as the odds are in my favor but I'd never devote my time and money into things I consider unworthy of the risk.
For instance, I'm more than willing to go sky diving or rafting, it sounds dangerous, but it's actually safer than most people think. However, I'd never risk money in High stakes gambling nor would I risk my life in stupid actions.
