cybernetic upgrades more comfortable

my brain cybernetically upgrades 

and my skull becomes damaged from those cybernetic brain upgrades 

then my skull cybernetically upgrades 

and my teeth are damaged from my cybernetic brain upgrades 

then my teeth cybernetically upgrades 

then my brain cybernetically upgrades 

and the cycle repeats itself, but in the future, 

possibly my skull and teeth will not be damaged any more from my cybernetic brain upgrades
