TOEFL Independent Essay. I am practicing for this test, so I would appreciate any comment ;-)
Why do you think some people are attracted to dangerous sports or other dangerous activities? Use specific reasons and examples to support your answer.
In the world we live today, there are several alternatives in order to practice sports or recreational activities. During last decades, extreme sports have become very popular. I am of the belief that people practice these dangerous activities for two main reasons, which I will explore in the following essay.
First of all, dangerous sports and activities provide people extreme sensations that cause pleasure. It has been demonstrated that extreme survival experiences trigger the production of adrenalin, which is the hormone associated with exciting experiences, that could be pleasant for some people. Extreme activities, such as bungee, skiing or skydiving, make people to face dangerous situations. As a result, human brain responds through signals in order to an especific gland generates adrenalin. Some people feel pleasure because of this hormone and they develop a kind of addiction. It has been well documented that when people realize they enjoy these dangerous activities, they tends to continue seeking for more and more extreme experiences. For example, a friend of mine started to practice bungee and then he incorporated more extreme activities such as skydiving. Now, he is looking for new exciting activities all the time. He is always saying that he needs this to feel alive.
Secondly, an important amount of people practice these activities because they are in fashion and for sharing these experiences in social media. It is not a secret that a lot of people do some activities just because other people do them or just with the purpose of being more popular in social media. In this regard, extreme activities are very well-considered between young people, therefore, they these sports are popular in social media with the goal of obtaining more “likes” and social approval. My sister is a compelling example of this. She started to practice these dangerous activities just because her friends practice them and in order to increase her popularity in Facebook and Instagram. As a result, she actually raised the number of her followers, in the same way that her friends had done it before.
In conclusion, I strongly believe that people practice dangerous activities because they provide extreme and pleasant sensations and because they are in fashion and are well-considered in social media.

An artificial uterus that saved the life of a lamb may be used in humans
A scientists team from the Children's Hospital of Philadelphia, PA, was able to keep alive premature lambs in an innovative plastic bag. This is a device that simulates the conditions of the maternal uterus, whose tests have gave very successful results.
In fact, a research published by Nature Communications magazine that uses data from the experiments, point pout that the scientists were able to keep alive premature lambs for four weeks. Although it is true that this had been previously tried, this is the first time that was successful. Unlike earlier tests that achieved to keep alive the animals just for 60 hours, the tests for this new device were capable to reach 28 days of survival.
According to the leader of the scientists team, the goal of the plastic bag is not to replace an uterus during the first pregnancy stages, but the purpose is to develop a mecanism to afford premature babies be treated. Thus, the objective is to produce the required conditions after the premature birth, in order to stabilize the newborn. In fact, first tests in humans are planned to be developed in a couple of years.

Are brown eggs better than white eggs?
Tradition says that brown eggs are more nutritive than white eggs, and hence, it is not surprising that they are more expensive in most of the places where they are sold.
However, this is not true: from the aspect of taste and nutrition, a brown egg is identical to a white egg. The colour of an egg is defined by the bree of the chicken. According to a mexican poultry, a white feather hen will lay white eggs, while red-brown chickens will provide brown eggs. Regarding to the colour of the yolk, this is determined by the corn quality used to feed the chicken, but it does not define the colour of the eggshell.
So why are brown eggs more expensive?
There are two explanations: first, brown chickens are bigger than white chickens, therefore, they eat more corn and hence, their eggs are more expensive. Second, due to the popular belief that brown eggs are better, they are in high demand that implies high prices.

Aftershocks may last up for month after the last earthquake in Chile
Several aftershocks have been generated by the 6.9 magnitude earthquake that struck central Chile, that caused fear but not damage to people nor facilities.
Although the USGS initially informed that the earthquake was 7.2 magnitude, the value was finally corrected to 6.9 by the Institute, just like local agencies had stated in previous reports.
The earthquake happened at 18:38 local time and the epicentre was near Valparaíso, a coastal city in Chile. According to a local agency, 148 aftershocks have been detected, the strongest being a 5.5 magnitude aftershock.
While it was informed that these events are a seismic swarm, this information was discarded by an important earthquake expert, who pointed out that the earthquake and its aftershocks are of different magnitude, while a seismic swarm is composed of similar magnitude earthquakes.
The last Saturday, a 5.9 magnitude earthquake and a serie of aftershocks ocurred in the same region during the weekend. This is not strange in Chile, one of the most seismic countries in the world.

A polar bear died of sadness
A 21 year-old female polar bear called Szenja unexpected died in the Seaworld Aquatic Park in San Diego, U.S. The death surprised the park carers, who say that the cause of death is still unknowned and it will take severals weeks to find it. However, it is thought that the death is associated to the fact that her partner who lived with her in the zoo, a female polar bear called Snowflake, was moved to other zoo in Pittsburgh, Pennsylvania. Szenja was separeted from her friend the last days of February. After that, she stopped eating and progressively lost energy until she died, just a week ago. Both bears had been together since 1997, when Szenja was moved to US from a zoo in Germany, where she was born. Snowflake was carrried to Pittsburgh with the purpose of being bred by a male polar bear.

What do you do on Saturday?
Saturday is a rest day for me. I usually wake up early in the morning but I often stay in bed several hours, using the laptop or cellphone, reading a book or sometimes just taking naps. Sometimes, I get up for having breakfast and then come back to bed, sometimes I do not get out of bed until 14:00 for having brunch. In the afternoon, I come back to life and I usually do leisure activities.
