Health Effects of Indoor Air Pollutants
Health effects due to indoor air pollutants may be short- as well as long-term. Short-term problems include a stuffy, odorous environment and symptoms such as burning eyes, skin irritation, and headaches.

Basically, The Chaos theory states that if we do not look after the pennies, we will never get rich.
For example (after every statement give proof)
If you are doing accounts and you leave out all the small amounts such as, .00035 + .00012 + .00076, or you leave out all the butterflies flapping wings, or you having passed wind. (Sorry! Fart was verboten) You will not have the correct answer. Hence, Your Results are never able to predict the weather… Continue

My favorite moment is when I sit on a chair with a book and a cup of coffee.
(About 1 hour later, I am so abosorbed in reading it that I find the coffe is already cold.)
These days I read novels when I have enough time.
But I don't know what novel is good or who the best writer is, so in a book store, I always take a look at information about best sellers and try reading them.
Then I've found that reading lets me forget something that always makes me depressed.

Tomorrow is April fool' Day. Is there anything special in your country?
I don't want to fool my friends, also not hope to be fooled by some friends. So it's normal as usual for me.
A good news for me is I've got a new job and start work from tomorrow, April Fool's Day.
Sounds funny, haha.
Wish you will have a funny day and won't be fooled and you will be successful to fool someone, lol...lol......

Today I would like to say to things.
First, I so happy because a family is together again. In my country, Colombia, there is a stupid war that seems endless. Most of people want peace but they have found in war a way to earn money and also power, so we are any closer to be in peace. However, it does not matter because today a soldier has been release from being kinapped for about twelve years. And his father is a teacher who walk across the country asking… Continue

Could we improve our speaking skills just by writing? I think so. Let's write a dialogue/dialog to see if it works - it can be called a speaking challenge. Continue
A dialog is just a conversation between two or more people. Here, we just try to write down what people may actually say in a conversation.
You can write a dialog:
·on any topic, as long as it's an acceptable one.
·between student and teacher, shopper and shop assistant, woman and man, patient and…

The world of mass communications has led among other things to a climate of fear around the world. In FEAR there is money. There is no money in safety. Furthermore, in FEAR there is control.
When was the last time you switched on the News and heard: "Good morning, this is the 9 o'clock News. There is no news today."
News stations have to fill a certain number of minutes with news, and they know that "no news is good news" so they have to fill those minutes with BAD… Continue

I was wondering the other day....
If man disappears from earth for any reasons, what will happen to our watery planet?
Among all the creatures that are living on earth we ( humans ) have the most effect on her, you can trace us almost anywhere from deep in the ocean to up in the sky and even in outer space.And we hurt her any way we can. To know what we have done to her we must imagine a world in which we do not live on earth anymore. What will happen to roads we have… Continue

With apologies to Yves St Laurent:

I would like to apologize to everybody who has read my blog. I have not done my best, for example, I have written a lot of bovine excreta for which I deeply and sincerely apologize. (I have this American dictionary that forces me to use American spellings) (A writer should ponder a one word which he uses for about 2 or 3 hours before he pens it (I have used the word pen instead of write to show I know English.)
I have decided to make up for this by teaching how to write an essay.… Continue
