Most of us usually listen to music for relaxation, but do we know that it can help (17) our overall health. Researchers at Stanford University have proved the (18) power of music. Happy, upbeat music causes our brains to produce (19) like dopamine and serotonin, which can be considered natural antidepressants. This leads to the clinical use of music to help those with psychological, cognitive or communicative needs.
One of the main reasons for the success of music (20) is that music keeps our cardiovascular system (21) tune. Performing or listening to music can affect our heartbeat, either accelerating it if there is a higher bpm on the track or (22) it down when we hear more relaxing beats.

Is it true that cold-blooded animals have no feelings and emotions? Many studies have been carried out to challenge the misconception. Scientists have made close observations about reptilian behaviors in the belief that they can measure reptile’s emotions if they can understand their body language. The findings are surprising that reptiles experience a wide range of emotions, and that they’re highly socially complex animals.
For example, crocodiles, known for their formidable presence, express maternal care that extends beyond mere instinct. Females carefully tend to their nests, adjusting temperature by adding or removing vegetation, and fiercely protecting their hatchlings, sometimes carrying them in their mouths to water for safety. Such behaviors indicate a form of maternal affection.
Another case showing emotional complexity in reptiles can be found in red-footed turtles. These creatures show signs of distress when handled roughly or placed in unfamiliar environments. Even snakes, often considered solitary and indifferent, show strong emotional reactions. When showing aggression, they tend to hiss, coil and shake their tails. With a wealth of aforementioned evidence and extensive studies, scientists hope that reptiles can be protected from habitat loss in the coming years.
