Understanding the Growth of Nose and Ears

The video debunks the myth that ears and noses grow continuously throughout life. Instead, they become stretchier due to collagen breakdown and reduced production as we age. Studies in the UK and Japan show a slight increase in ear length over time. UV exposure accelerates collagen degradation, making ears and noses less sturdy. Gravity also contributes to their elongation. Despite using sunscreen, these changes occur, leading to the appearance of growth, which is actually due to structural changes.

What is the common misconception about the growth of noses and ears?

• They shrink as people age.

• They become stretchier rather than growing.

• They remain the same size throughout life.

• They grow larger due to increased bone size.

Which countries conducted studies on ear length changes over time?

• Australia and New Zealand

• Germany and France

• United States and Canada

• UK and Japan

What material in the body is primarily responsible for the structure of noses and ears?

• Fat

• Cartilage

• Bone

• Collagen

How does UV exposure affect the ears and nose?

• It makes them grow faster.

• It has no effect.

• It strengthens them.

• It speeds up collagen breakdown.

What happens to collagen production as people age?

• It increases significantly.

• It remains constant.

• It decreases, leading to less replacement.

• It stops completely.

What is the primary reason for the change in ear and nose size over time?

• Increase in bone density

• Destruction and stretching of existing tissue

• Accumulation of fat

• Actual growth of new tissue
