&gt; A 1&#x2F;10000 chance of certain death doesn&#x27;t sound like something I&#x27;d like to take.<p>(maybe I was a little bit off, it&#x27;s more likely that the risk of failure is 1&#x2F;1000, so sum is 1&#x2F;1.000.000)<p>but the point is, it&#x27;s more risky to drive back home after the weekend than to recreational cave dive, especially with dive fatigue!
