Baroness Greenfield, junk neuroscience, and the dangers of video games



Technology has become a major part of the majority of our lives. We spend our spare time in front of the screens to get rid of our stress from a long period of working or to just kill some time, which is quite normal for not just the teenagers but also everyone nowadays. However, according to the former director of the Royal Institution, Baroness Greenfield, video games as well as other technological recreations are deteriorating our brains and damaging the nerve connections in the brain.
Greenfield says that the technology, such as video games, which sometimes strongly affects the sense, could give a temporary or permanent damage to our brain nerve connections, and could addict people to have more screen-based lives. She also says that people would get a habit of sitting in front of a screen for a long time instead of doing activities and the average child would spend approximately 2,000 hours with such technology between his or her tenth and eleventh birthday.
Of course, this report about such negative effects of video games and technology on the brains is probably written to aim at the teenagers rather than other age groups. Yes, Greenfield focuses more on the negative impact of video games than actual technological devices. However, technology is now one of our most important necessities and few people spend time in front of a screen to the point where they could actually “damage their brains”. The majority nowadays do spend their leisure time on their phones, tablets, computers, etc. for their entertainment or relaxation. Spending 2,000 hours in front a screen in a year means that one would spend five and a half hours every day, but it doesn’t necessarily imply that he or she games for that long every single day. Such technology could be addicting and attract our hands anytime, but this is the reality; we are all already living in the screen-based world in which the technology plays a major role.
This report written by Greenfield is quite ambiguous and not persuasive enough in terms of clarity of each point. However, this provides us a good opportunity to just ponder carefully about how much time we spend using our technological devices and to remind ourselves of how to use not only the time but also our technology effectively.

Cats VS. Dogs


People are always arguing about whether cats are better than dogs or vice versa. Although mostly everyone’s choice is their personal opinion, there have been many studies and surveys conducted that show how cats and dogs can affect your life so maybe, it can help you choose which kind of animal you want as a pet when you have to decide between buying a cat or a dog.

In America, around 77.5 million people own dogs while a much larger number of 93.6 million people own cats. The upkeep for a cat generally costs less than a dog and recent studies from the University of Bristol in England showed that people who owned cats are more likely to have university degrees than dog people. On the other hand, a study from Queen’s university in Ireland said that people with dogs have lower blood pressure, cholesterol, and suffer fewer serious medical problems so they are usually healthier. Ownership of a dog can lead to increases in physical activity, which results in better fitness. In another survey with 4,500 participants, people answered questions about their personality and the results were that people who possessed dogs tend to be more social and outgoing while cat people are more likely to be creative and philosophical. This could be because dogs are companionable and enjoy being with their owners while cats usually keep to themselves and if they hang out with you, they leave whenever they feel like it.

Dogs and cats have a bigger role in your life than you think they do. They are not just cute and cuddly and nice to have around but they also help you in different ways. Hopefully, this can give you a little more insight into whether owning a dog or a cat is better for you.
