Why Isn't Life Immortal? - Lesson Plan

The video explores the fascinating aspects of life, focusing on metabolism and aging. It explains the processes of anabolism and catabolism, and how metabolism is the sum of these processes. The video discusses theories of aging, such as the rate of living hypothesis and oxidative stress hypothesis, and their limitations. It also highlights species with long lifespans and the concept of immortality in nature, including sponges and the immortal jellyfish. The relationships between metabolism and aging are complex, with ongoing research adding to our understanding.
