Statistically speaking, you’re probably not going to die playing a sport. That bing said there are some sports that are way more dangers than others. BASE jumping and mountain climbing above 6000m in the Himalayas (think climbing Mt. Everest) will certainly increase your odds of being killed. Other activist such as going to a dance party have a higher likelihood of killing you than say going snowboarding.
The real killers, as the infographic below from Best Health Care Degrees, are smoking and obesity. So go out there and have some fun.
