The vital part of the human body

What can you do without a brain?

The text discusses the concept of a "no-brainer" and explores various examples to determine if such a thing truly exists. Here's a summary of the main points:

1. **Mike The Headless Chicken:** In 1945, a farmer beheaded a chicken named Mike, but the chicken survived for another 18 months. The narrative argues that this wasn't a true "no-brainer" because Mike retained a part of his brain stem.

2. **Cockroaches:** Cockroaches are cited as an example of creatures that can survive without a head. They breathe through holes in their bodies and have nerve ganglia distributed throughout, allowing them to live for weeks even after decapitation.

3. **Human Reflexes:** The text touches on human reflexes, such as snapping fingers or sneezing, which can be considered actions that don't necessarily require conscious brain involvement.

4. **Behavior After Death:** Even after death, certain behaviours can occur. For example, insect parts or frog legs can exhibit responses due to residual energy in cells. Skin cells can continue living for some time through osmosis and division, and bacteria in the gut may continue the digestive process.

5. **Philosophical Considerations:** The text delves into philosophical questions about identity, asking whether skin cells and bacteria continuing their functions after death can still be considered "you."

6. **Existence as a Yes-Brainer:** The text concludes by suggesting that a true "no-brainer" may be impossible for humans because, if identity is solely defined by the brain's actions, being alive and conscious is a "yes-brainer."

The narrative explores the concept from various angles, blending scientific examples with philosophical pondering. If you have any specific questions or if there's a particular aspect you'd like more information on, feel free to do some personal research!
