Being young is associated with risk-taking (see http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2396566/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2396566/ for instance for some references. In the article, "young" means less than 25). So you're more likely to ski less safely, for instance. Young drivers are also really more likely to have a car accident (ask car insurance), not because they are this age or that age, but because they less experienced.
