Junk e-mail is better than junk mail
As more and more people use the internet, we receive increasing amounts of junk e-mail.
With computers becoming more powerful and databases larger, new opportunities arise for direct mail companies to expand their mailing lists. Bulk mail can be sent out based on location and demographic data. This makes marketing more targeted and increases response rates.
Junk mail not only promotes products, but is also used in politics. Barack Obama's presidential campaign distributed mail to voters, encouraging them to support his team.
Junk e-mail and mobile phone messages can be annoying, but at least they are better than the junk mail that clutters letter boxes.
Environmental groups have expressed concern about the impact of junk mail. It is a terrible waste that trees are chopped down for paper most people simply discard.

Let's not always be attacking each other
There's an old saying about how we can learn something from everyone. But this seems to be less and less the case. People these days spend more time looking for things they can attack others about.
In the workplace, people try to find others' weaknesses to attack them and be promoted. At school, some students attack others to create a good impression on teachers.
This is wrong. We do not need not to wear masks and have our weapons ready all the time. If we treat others with sincerity, we might find we do not need a mask or a weapon because we will not have any enemies.
If we are always ready to go into battle, we will constantly be tired from fighting for nothing. Open your mind for friends, not battles.

Moss missteps on the skinny factor
I recently read on www.celebrity-gossip.net that Kate Moss said in an interview: 'Nothing tastes as good as skinny feels.'
Representatives of eating-disorder groups were quick to call Moss irresponsible, reminding her that many young people struggle with eating disorders.
I was also shocked, because Moss is 35 years old and she should know the importance of thinking before speaking. What's more, she's a mother, so she should know how impressionable young people are.
Teenagers in Hong Kong all want to be skinny. Mostly, it is due to the influence of skinny celebrities.
Young people want the 'celebrity look' and will do anything to stay slim - even to the point of damaging their own health. There is no sense to this.
Celebrities should think about the influence they have when they speak in public.
Read the labelling of 'health' drinks
We all know it is not good for us to drink soft drinks as they contain a lot of sugar. But some drinks we consider 'healthier' might not be as healthy as we thought.
The Consumer Council recently examined 80 beverages and found that some of them contained large amounts of sugar.
Among the 80 drinks tested by the Council, Yakult was found to have the most sugar - a bottle of it represents 32 per cent of a person's recommended daily sugar intake.
The message for us as consumers is to carefully read the label on drinks we buy. Drinks we think of as healthy - and perhaps drinks that even advertise themselves as healthy - may not be quite as healthy as we thought.
