Biden and his loss of 'grip' when debated and the disorder of selfhood

Why Biden is being protected from debating Trump is this loss of mental 'grip' when confronted
so why is this?
There is a word ipseity (a fundamental and pre-reflective awareness of self)  and for some who are cognitively challenged,  (SAY BIDEN OR ALL OF THOSE APPROACHING 80)THIS FUNDAMENTAL AWARENESS OF SELF IS UNDERMINWS (the brain ages like all our organs IS A machine which runs down.
