Can You Really Die of Old Age?

The video explains that dying of old age often means dying from complications related to aging, such as diseases a younger person might survive. Cellular senescence, influenced by telomeres, is a key factor in aging. Other contributors include oxidative stress and glycation. While antioxidants can help, aging effects are inevitable. Age-related diseases often lead to death before cellular senescence can. As people age, their immune systems weaken, making them more susceptible to diseases like Alzheimer's and heart problems, which become the direct cause of death.

What is the primary role of telomeres in cellular aging?

• To increase the lifespan of cells

• To protect genetic material during cell division

• To accelerate cellular senescence

• To repair damaged DNA

Which of the following is a factor that contributes to cellular aging?

• Enhanced DNA replication

• Improved immune response

• Oxidative stress

• Increased cell division

How can antioxidants help in combating cellular aging?

• By shortening telomeres

• By reducing oxidative stress

• By enhancing cellular senescence

• By increasing glycation

What happens to the immune system as a person ages?

• It becomes stronger

• It remains unchanged

• It becomes more efficient

• It weakens

Which of the following is NOT a disease commonly associated with aging?

• Alzheimer's disease

• Chickenpox

• Heart problems

• Blood pressure issues
