Stop tinkering with the ageing process
According to new research, our brains start degenerating at the age of 45 - much earlier than age 60 as previously thought.
Many scientists are working to help us keep our mental functions as long as possible. They are trying to invent some medicine to do so.
I am opposed to this idea. It is natural that our bodies, including our brains, should degenerate over time.
We have no right to tinker with nature's designs. Besides, keeping people alive longer will only worsen overpopulation.
We should not interfere with the process of natural ageing.

Embracing change is part of life
I was listening to the song Still by Ben Folds from the soundtrack to the animated film, Over the Hedge.
The movie is about a group of forest animals facing challenges in their hunt for food. The lyrics go: 'Even the stars above / things that seem still are still changing'.
I find the words really inspiring.
I am scared of change. It means being out of my comfort zone like coming across new people or ending up in new places. There is something new everywhere I look.
I guess, though, that adapting to change is vital in today's world. Even if change means we have to make compromises. Everything is changing all the time, yet that's how we move forward in life.
A New Year has just arrived and one of my resolutions was to embrace change and take chances.
We have to grab a cup full of faith. Just like Matt Damon's character says in another movie We Bought a Zoo: 'Sometimes all you need is 20 seconds of insane courage.'
That's how we can make something amazing happen. I am going to give change a chance.

Bullfighting is a cruel blood sport
I recently saw a photo of a matador attacked by a bull during a traditional year-end bullfight.
I do not approve of this cruel blood sport.
I know bullfights are part of Spain's heritage and traditions. Yet I feel people's safety should outweigh the entertainment factor.
Animals should not be made to suffer needlessly, either.
It may be hard to change an old tradition such as bullfights in Spain. But it's not impossible.
Education is the best policy to help people understand the health risks and safety issues involved.
This cruel blood sport will have to change.

I hope the world doesn't end this year
According to an old Mayan prophecy, the world will end this coming December.
Many people dismiss such fears, but I am concerned. It's not that I am afraid of death; it's that I do not want to be separated from people I love.
I want to spend many more years and share many new experiences with them.
Yet whether the end comes this year or not, we have to realise that we simply just cannot control some things in life.
We have to live our lives by treasuring every day we have.
We should be passionate about everything in our lives and seek to create memorable experiences.
Let us live every day as if it was our last. That way we will cherish life and enjoy it to the full.
Luxury shop should not discriminate
Dolce and Gabbana is a shop located in Tsim Sha Tsui. It recently stopped a Hong Kong citizen from taking photos at the shop.
Some people suggested that a high-ranking mainland officer may have been shopping there at that time and he did not want to be seen buying luxury goods.
Many Hong Kong people thought this was 'racist'. Some of them recently held a photo-taking demonstration at the shop.
Other people expressed support for the demonstration on the internet. They are organising more demonstrations at the shop.
Dolce and Gabbana is a world-famous shop. It should not make locals feel discriminated against.
The shop's managers owe us all an explanation.
