yep and I have had a colleague who was 35 years old and crashed without a mayday or from what they can tell any control input.
Who says you can flip the trigger. Stroke is the biggest killer of pilots sitting at the controls, some have even just walked out of their medicals that morning and bang the FO is now PIC.
bang your head off the roof as the AP kicks out again no trigger.
But your PIC so its your choice what you do.
