There are plenty of sports available which are challenging, competitive, and entertaining . . . yet, neither require nor cause any of the aforementioned actions be directed toward another player (or players).
Yes, there are plenty of sports which are “challenging, competitive and entertaining†but, unfortunately, many of those have a downside of injury and death. So, let’s just err on the side of caution and ban every sports activity where there is a history of injury or death, whether by intention or not. These statistics
from the Insurance Information Institute provide a good starting point.
I note that, according to a National Ski Areas Association (NSAA) Fact Sheet, during the 10 years ending in 2017, 38 people died skiing or snowboarding per year on average. Gee, more dead every two years than in 93 years of boxing.
