Can leaders (U.S. Presidents, Board Directors, CEOs) have an “Off Day”?

#1 In the June 27, 2024 debate between President Biden and Donald Trump, President Biden showed signs of mental issues and cognitive decline.  What if during those 90 minutes, there’d been a crisis, and President Biden had to make the decision on whether or not to launch nuclear missiles? U.S. Presidents sometime need to make momentous decisions with limited preparation time. Given the impact of these decisions, should U.S. Presidents be allowed any “off days” when they have degraded mental capabilities?

#2 Are company board directors allowed to have “off days”?  Should a board director be allowed to make decisions (e.g. CEO appointment, CEO termination, accepting/rejecting M&A offer, etc.) when their mental capabilities are degraded? If not, what processes does your board have in place to prevent this?

#3 Are company CEOs allowed to have “off days”? Should your CEO be allowed to: make recommendations (e.g. presenting strategy to the board of directors), decisions, and communications (e.g. live global virtual town hall) when their mental capabilities are degraded?  If not, what processes does your board have in place to prevent this?
