The possibility of something unwelcome or unpleasant happening.
Sticking to the meaning of the term, as it is indicated in the dictionary, all our physical activity (whether cooking, walking or extreme sports) is more or less predictable, and due to the presence of even the slightest factor of unpredictability is in itself risky.
Therefore, since every activity is intrinsically risky, what procedure do we use to label some of them as dangerous and others as not?
The answer lies in the continuous search for simplicity, in an unreasonable conclusion. In practice, when we witness a dangerous event or accident, instead of contextualising it, we express an overall judgement of such activity or sport as a whole. It doesn’t matter whether it is virtual (YouTube) or real.
It’s no coincidence that those who judge, for instance, kiteboarding as a high-risk sport, usually tend to give the same examples, which are not based on the context.
But it is not and must not be so easy to draw conclusions.
