Alzheimers or senile dementia is obviously much more likely in a person of advanced age so it is certainly a good argument.
Of course there are cases of dementia in middle age but extremely rare and you and I both know there is no way of checking what's going on between pilots ears at medicals.
An accident caused by a mentally impaired aged pilot (and there will be one) will be so sensational the public will demand answers.
Flying aeroplanes is not a job for old people. 65 is more than enough.
