Read the following passage carefully and answer the questions given below it. Certain words have been highlighted for your attention.

Most people spend (on average) half of their day tapping away at their hand-held devices. Either, surfing the net or checking notifications. Facebook ranks the highest in all social networking platforms, followed by Twitter, Instagram and so forth.

Social media is addictive- which is why so many people are 'hooked'. Often referred to as Social networking addiction, this phrase is often used to describe someone who spends too much time on Facebook, Twitter, Instagram and other channels. A blog post, Instagram post, tweet, or youtube video can be produced easily by anyone and shared, which can then be viewed by millions for free. Psychologists and scientists have now taken the time to study social media in terms of why they believe it interferes with aspects of our daily life. There is no official medical term that identifies addiction and social networking. It cannot be deemed as a disease or disorder as the cases are not severe and the habit can easily be maintained or prevented. Furthermore, instead of spending long periods of time on social media, we dip into and out of these sites all day long. We check for updates from friends and family as well as news and information. However, the behavior associated with the excessive use of these channels has become the subject of much public and sociological debate. We actively post, like, comment and share personal posts. Not only that, we tend to share and reshare expressions (of either negative or positive) contagiously. But, why?

Scientists believed some years ago that, dopamine was simply a pleasure chemical in the brain. Recent studies have shown that; dopamine actually produces the desire in people to 'want' by drawing out the need for us to -seek and search. Creating the ultimate drive to find what is that what we want.

Dopamine is spontaneous. It’s stimulated by unpredictability and small bits of information as well as reward cues which are the same conditions that social media presents to all users. In addition, the pull of dopamine is so strong that recent studies have shown that tweeting, for example, can be harder to resist than cigarettes and alcohol!

Researchers at Chicago University studied the effects of social media. They concluded quite quickly that people presented higher levels of addiction to social media than the need to smoke or drink. Media cravings ranked higher.

And, let’s not forget oxytocin, many call it the cuddle chemical because the brain releases pleasure chemicals that transpire usually when you kiss and hug- or tweet. It is also known as the hormone that builds the strong yet unique bond between mothers and their babies. Oxytocin is now regarded as the human stimulant of empathy, generosity, trust, and more. These are factors which many advertisers and marketers play on when promoting a brand or business over social media.

Nevertheless, problems have arisen most commonly with school kids - whereby mobile phone devices have been confiscated because exam results have fallen severely due to lack of attention on homework or studies. Schools in many westernized countries have had to take drastic action - banning smartphones, iPad and most portable devices from school premises- as it is claimed to be a huge distraction. Whereas, other schools use it for educational purposes and as a rewards system for their pupils.

Research has also indicated unsurprisingly that Facebook is the most common activity that university students switch to, when studying. Worryingly, it has also found that those who most engage in this type of internet browsing tend to have lower levels of educational achievement.

Also, there have been many cases of students posting or sharing content that is unethical, which has caused parents and academic institutions to limit the use of these online networking channels.

Why is Oxytocin regarded as the cuddle chemical?

The number of Indian students going abroad for higher studies has increased by 68.79 per cent in the past year, according to data provided by the Minister of State in the Ministry of Education, Subhas Sarkar. As per the data provided by him in the Lok Sabha, the number of Indians enrolled in foreign varsities increased from 4.44 lakh in 2021 to 7.5 lakh in 2022. He clarified that while the Bureau of Immigration and Ministry of Home Affairs maintain departure and arrival data of Indians, there is no index for capturing the category of Indians going abroad for higher education. “Purpose of Indians going abroad for higher education is captured manually based either ontheir verbal disclosure or the type of visa of the destination country produced by them at the time of immigration clearance,” Sarkar said. According to the data provided by the ministry, the number of Indian nationals increased from 4.54 lakh in 2017 to 5.17 lakh in 2018. There was a significant increase in 2019 as well, with 5.86 lakh students flying out of the country. However, during the Covid pandemic, the number of Indian nationals in foreign varsities saw a drastic dip as only 2.59 lakh students were registered. While the number continued to remain low, it saw a slight increase in 2021 with 4.44 lakh registrations. However, the number has significantly jumped to 7.5 lakh in 2022. The increase in the number of Indian nationals abroad corresponds with the latest immigration reports from some of the popular study-abroad destinations such as the US, UK, and Australia. For the UK, the Immigration Statistics Report states that 127,731 visas were granted to Indian students in September 2022, an increase of 93,470 (+273 per cent) against 34,261 in 2019. Similarly, in the US, the number of Indian students has more than doubled, and the Open Doors Report 2022 has predicted that the number of Indian students heading to America is likely to surpass those from China in 2022-23.

How do we know the number of students getting visas for studies in UK?

The most logical and intelligent people seem to go berserk when talking about snakes. Recently a reputed scientist said with a wise look in his eyes that sand boas have two heads. The other day someone walked into my office and stated that in his village at least cobras mate with rat snakes. About other places he was not sure, he added modestly, but that was how it was in his village.

These stories about snakes are myths. Sand boas have only one head; vine snakes do not peck your eyes out; no snake will drink milk. But it is interesting to try and trace the origin of these untruths. The one about the sand boas two heads obviously exists because the short, stumpy tail of this snake looks remarkably like the head, an effective device to fool predators. Or take the one about vine snakes pecking at eyes. It was ‘probably started by a vine snake that had a bad aim, as snakes, when provoked, will bite the most prominent projection of the offender, which is usually the nose.

But the most interesting one is about snakes coming to the scene of killing to take revenge. It so happens that when injured or under stress, a snake exudes, a large quantity of musk. Musk is a powerful sex attractant, the snakes’ equivalent of after-shave lotion. So after a snake is killed, the ground around still has this smell and naturally a snake of the same species passing by will lick its lips and come to investigate. The killer of the snake, who is probably worried if the pooja he performed was adequate to liquidate the killing of a snake, sees the second snake and is convinced that it was not.

The Irula tribals have a good answer to the query about whether cobras have jewels in their heads; “If they did, we wouldn’t be snake catchers, we would be rajas!”
