ELI5: Why do we subconsciously immitate others' body gestures?
gpt
It helps us feel empathy for others. When you talk to another person, you will also subconsciously imitate their facial expressions. The small changes in muscle tone of your face muscle will send feedback to our brain which can identify the corresponding feeling better. Infact, experiments have shown that people who use BOTOX(a chemical which is a toxin to nerves that is injected to your face to remove wrinkles. No working nerves serving the facil's muscle= lesser skin stretching= lesser wrinkles formed) will show a lesser degree of empathy compared to those who did not use BOTOX.
