Forum: Civic-mindedness in Singaporeans growing

I was with my family to watch the live telecast of the National Day Parade at the OCBC Arena last week.

Besides being treated to a variety of fringe activities and performances, as well as the fantastic parade, what heartened me was that after the event, everyone in the area I was at bagged their garbage and placed them in the rubbish bins provided. There was no rubbish left behind.

I have observed signs of an increasing civic-mindedness in our country.

For example, I have noticed that more and more people are cleaning up after themselves at hawker centres, giving way to other signalling motorists, moving in on buses and trains to make room for other passengers, and the like.

This clearly demonstrates that even as our country is prospering on the economic front, our social etiquette and consideration for others are also improving tremendously.

The only bugbear that I still have is that many people still talk during movies.

Strong sunlight can kill your hair

morning sun - it is going to be another hot day

Sunlight is pretty energetic. It will destroy some plastics causing them to fall apart and crack. In chemical terminology, the ultraviolet radiation in sunlight ruins things by oxidizing them.

Our hair will sacrifice themselves to save our brain. If we do not have hair, our brain will fry in the strong sunlight.

The sun bleaches and destroys the melanin in your hair giving you lighter hair. Since hair is dead, the hair will stay that color until new hair comes in.

A simple advice from a doctor:
"Tanned skin and bleached hair may be a sign that someone is spending too much time in the sun. Try to keep your skin light and your hair dark by wearing sunscreen and a hat!"

Very low salt intake may be as bad as high levels


Diets which are very low in salt, or very high, both appear to be harmful according to a large international study which claims most people’s intake doesn’t appear to increase risks of heart problems.

The NHS recommends adults should eat no more than 6g of salt per day, and that above this level salt in the diet will lead to high blood pressure and increased risk of heart attacks and stroke.

But a study published in The Lancet medical journal on Thursday, which followed the diets of 95,767 participants in 18 countries, argues that regularly eating between 7.5g and 12.5g of salt (2g to 5g of sodium) a day makes little difference.

The authors go as far as claiming that very low levels, below 5g, of salt appeared to put people in the study at greater risk of cardiovascular disease, but this has been contested by other researchers.
