Q2: Can the human brain really be cut in half without affecting its function?
A2: The human brain is incredibly resilient. In some rare medical procedures, such as a hemispherectomy, parts of or an entire hemisphere of the brain can be removed to treat severe neurological conditions without completely impairing the brain’s function. However, such surgeries are complex and have significant implications.
Q3: Is it true that humans can’t smell while sleeping?
A3: According to the study mentioned, people didn’t wake up when exposed to smells during sleep. However, this doesn’t mean that our sense of smell completely shuts off. It’s more about the brain’s response to stimuli during different sleep stages.
Q4: Are all bacteria transferred during kissing beneficial?
A4: While many bacteria transferred during kissing are harmless or even beneficial, it’s still possible to transmit harmful bacteria or viruses. Good oral hygiene and overall health are important to minimize any risks.

Q7: Why do women blink more frequently than men?
A7: The notion that women blink twice as much as men is actually a misconception. Studies indicate that there isn’t a substantial difference in blinking frequency between genders or across different ages. Interestingly, one study did find that women taking birth control pills blink 32% more than those not on the medication. This increased blinking rate might be linked to higher levels of estrogen in their systems.
Q8: How accurate is the fact about the human heart pumping blood up to thirty feet?
A8: This fact is more of a theoretical illustration of the heart’s power. In reality, the heart pumps blood through the circulatory system, which is a closed system, and doesn’t propel blood through the air.
