[Basic_Strategy]

Gov initiate a integrated systems to link up each household utility/water, mobile network, immigrations and family member contact.

assumption: every old folks need to use the toilet within 24 hrs wan
utility company systems detect NO usage of water of this unit for last 24 hrs > route to mobile company check any usage of the owner, if NO usage for last 24 hrs too > immigration systems check if user leave country, if NO then > system auto msg family member >if family member Non contactable > SCDF breakdown the door leow

famiy member could choose to opt in for such initiative else some ppl might GGYY police state

This is actually a good idea, and it's not police state stuff. 

Can support this.
