Falling in love is a universal fact. It has a power that is often beyond our control. But why do people fall in love, and how do they choose the people they love?

According to American psychiatrist Thomas Lewis, people fall in love due to their childhood experiences. In his theory, he argued that our brains remember how comfortable it was to experience physical closeness as a child, such as being held in a mother’s arms. As we get older, we seek the same experience, and when we love someone, we hope to go back to the past and enjoy the same comfort and affection again.

On the other hand, genetics theory states that we are attracted to people who have different types of genes from our own. This is because combining different types of genes strengthens the immune system. According to a study, a woman is more likely to have a healthier baby by choosing a man with genes different from hers.

Lastly, Helen Fisher, an American researcher, found that when people are in love, their brains release a lot more dopamine. Dopamine is a chemical that is released when we engage in an exciting or enjoyable activity.

Which theory do you think best explains why we fall in love?

Martine Rothblatt believes that “mind clones” will be humanity’s biggest invention within twenty years. The concept of cloning human brains for robotic bodies to use has been described numerous times in science fiction works.

However, Google director Rey Kurzweil said that our bodies could be replaced by machines within ninety years. Some people may even be digitally immortal. His 1999 book, “The Age of Spiritual Machines: When Computers Exceed Human Intelligence,” mentions one possible future of blurring boundaries between human intelligence and artificial intelligence. World problems such as hunger, war, and pollution can be solved if super-intelligent transhumans become hundreds of times smarter. On the other hand, computer-based intelligence acting “fairly” by human standards may not be guaranteed. Kurzweil mentioned that humans who become part of AI systems in the late 21st century might regard ordinary humans as second-class citizens. Furthermore, ordinary people may not be able to keep up with super-intelligent transhumans.

If “mind clones” become possible in the future, would you like to purchase a robotic version of yourself?

In less than a century, the word “organic” became a symbol of quality and tradition. In recent years, many organic products have appeared in shopping areas and superstores, claiming they are “100% organic” and have “no artificial additives.” But do they truly help the environment? Are they better for your health? They may cost twice as much, but how can we check what you are getting and if they are worth the price?

The largest sector of organic products still belongs to food. Supporters claim they taste better and are better for people. Critics, on the other hand, say there is no nutritional difference. The public demand for such products has increased drastically due to fear of the possible health risks of chemical pesticides. Consumers believe that pesticides can cause cancer, especially in children. But scientists claim that the fear is exaggerated.

There is still reason to be cautious, despite denials by many scientists. A recent study showed that 203 out of 957 non-organic foods tested and still had some pesticides. This includes nearly all the bread tested. Still, other scientists claim that our understanding of pesticide effects on humans is very limited.
