I asked ChatGPT, because everyone knows it is a source of reliable and not hallucinated information.

The human body has a remarkable capacity to heal itself, but the rate of healing can vary depending on the type of tissue and the extent of the injury. While it is true that the tongue, due to its rich blood supply, has a relatively fast healing process compared to other parts of the body, it doesn't mean that the entire body would be unable to maintain its energy if it healed at the same rapid rate.

The healing process requires energy and resources, including nutrients, oxygen, and metabolic activity. When a specific area of the body is injured, the body redirects resources to that area to facilitate the healing process. In the case of the tongue, the abundant blood supply helps deliver these resources efficiently, allowing for a faster healing time.

If the entire body were to heal rapidly at the same pace as the tongue, it would require a significant amount of energy and resources. However, the body is highly adaptive and has complex systems in place to regulate energy usage and resource allocation. It prioritizes healing based on the severity and urgency of injuries, allowing for a balanced distribution of resources throughout the body.

It's important to note that healing rates can vary based on factors such as the type of tissue, the extent of the injury, individual health conditions, and other variables. While the tongue may heal relatively quickly, other parts of the body have their own healing mechanisms suited to their specific functions and requirements.

Overall, the human body is designed to efficiently manage healing processes while maintaining energy balance and overall health.
