Should hawker centres charge a refundable nominal fee for trays? Will this spur people to return their trays after their meals?

I think the $1 refundable deposit at Timbre+ is pretty cool. Incentivise the whole concept. Same with supermarket trolleys - you don't see people leaving them around, as they'd rather get their $1 back.

How about we move away from solutions that use monetary penalties as disincentives? Instead, we can spend more effort on making systems that people will feel proud to use.

Make the tray-return system clean, easy and fuss free. Make sure the return points never get overloaded with uncleared utensils. Make sure it is easy to walk there with the tray, you don't have to wait to dispose of the tray, and you never get soiled by leftover food scraps.

Learn from Japan and teach our children the correct values in school. They will pass them on to the next generation.

This idea shows we are able to return our trays but choose not to. Large segments of our society are already returning trays - in schools, camps and even private office canteens.

So, for those unwilling to return trays at hawker centres, we should just fine them, just as we fine those who do not flush after using our public toilets.

Do you agree that the careless disposal of confidential documents is as serious as cyber breaches? What can be done to address this risk?

Of course. There is a need to create more awareness that documents which contain confidential information such as IC number and date of birth should be shredded instead of being dumped in a wastepaper bin.

To be fair, you cannot run a program over thousands of printouts looking for keywords and data, like you can with electronic files.

Physical hard drives (from defunct equipment) sold second-hand are a larger threat. The printouts seem less of a concern in real terms.

What's serious is that companies cannot afford paper shredders for the office. Heck, I have my own shredder at home.

Should work-life balance be a factor when doctors choose a speciality? How can young doctors balance altruism and family time?

Once you decide to take medicine as a profession, work-life balance is something that will be a challenge. Specialisation does not change this fact. A general practitioner works weekends and at night. General physicians in hospitals also do calls and attend to patients 24/7.

Philip Wong

It is only fair for doctors to choose a speciality that gives them the work-life balance they feel they need, just like the rest of us. It could help to give doctors time to recharge and come back fresher and stronger to see to the needs of their patients.

At the end of the day, only the love of spouse, children and family matters. No one on the brink of death regrets not clocking in more overtime hours. Most, if not all, regret not having cherished or appreciated their loved ones more.
