The video documents a 36-hour sleep deprivation experiment to observe its effects on the brain and body. Participants Taylor, John, and Melissa reach the halfway point and undergo an alertness test involving holding an egg on a string. John fails the test due to brain shutdown and post-meal drowsiness, highlighting the impact of sleep deprivation and heavy meals on alertness.

What is the main objective of the 36-hour sleep deprivation experiment?

• To observe the impact of sleep deprivation on the brain and body

• To study the benefits of sleep

• To measure the amount of sleep needed for optimal performance

• To test the effects of sleep on memory

At what point do participants start to feel the effects of sleep deprivation?

• After 12 hours

• After 24 hours

• After 36 hours

• After 18 hours

What is the purpose of the egg test in the experiment?

• To test alertness and detect dozing off

• To measure hand strength

• To evaluate memory retention

• To assess coordination

Why did John's brain cause him to drop the egg during the test?

• He was distracted

• His brain shut down nonvital areas

• He was too confident

• He was not holding the egg properly

What was John's initial confidence based on?

• His ability to stay awake for long periods

• His physical fitness

• His previous experience with sleep deprivation

• His knowledge of the experiment

How does eating a large meal affect alertness?

• It improves brain function

• It diverts blood and energy to digestion, reducing alertness

• It has no effect on alertness

• It increases alertness by providing energy

What happens to the body after a big meal, especially when sleep-deprived?

• The brain receives more blood

• The digestive system receives more blood and energy

• The body becomes more alert

• The body becomes more energetic

Why might someone feel tired after eating a heavy meal?

• Because the brain is more active

• Because the body is digesting and less blood goes to the brain

• Because they are not used to heavy meals

• Because they are well-rested

What is a potential reason for John's failure in the alertness test?

• He was not interested in the test

• He had a large meal before the test

• He was distracted by other participants

• He was not holding the egg correctly
