Odds of dying: 1 in 116,945
At first sight, tennis may look like one of the safest sports to practice. What can go wrong in a game where two players don’t have direct contact with each other? It is always possible that a ball hit you, but chances that the hit will be fatal are pretty low. However, according to Bandolier, there were 15 deaths on tennis fields in Germany between 1997 and 2006, which means that chances of dying during a match are one in almost 117.000. As in the case of the marathon, the most common cause of death is a cardiac attack. So if you are considering taking up tennis, first make sure that you heart can take it.
