When I rebuilt my inground swimming pool at my last house I was told by my home insurance provider to definitely NOT put a diving board OR a slide because of liability.
They also said do not buy a trampoline, scuba dive, jump out of airplanes, rock climb or have sex with other men. They all were very risky.
The most dangerous thing a person can do is be born on this Earth. Apparently the insurance companies want to discourage that too.
