There is always the "pampers" for Adults for the President.
If he should turn senile during his next term in office, we could
move the President's chair to an "Old Folk's Home" - where he could
have more company with people of his age during the day, and he
will not be so lonely in the big mansion on the Istana
grounds.
Even if he should suffer from dementia and lose his way in the
sprawling grounds of the Istana, fortunately it is surrounded by
new fencing, and the number of Gurkha guards and Police, and his
very efficient Aide-de-Camps will probably be able to find him and
lead him back to the Mansion.
So long as he does not go around and cause annoyance and
embarrassment to the good name of Singapore - by pinching the
bottom of the ladies, who are "tai-tais" of some other VIPs
(locally or from Overseas), we could still keep him as
President.
