Meta warns of the risk posed by Mark Zuckerberg practicing combat sports. The warning to investors in the company's annual report comes after Elon Musk's challenge to a fight that never happened.

“Mr. Zuckerberg and certain other members of management engage in a variety of high-risk activities, such as combat sports, extreme sports, and recreational aviation, which carry the risk of serious injury and death. If Mr. Zuckerberg were to become unavailable for any reason, there could be a material adverse impact on our operations,” the company says in its annual report.
