Why do some peoples' eyes twitch when they're angry?

Eye twitching when someone is angry can be attributed to stress and muscle tension. When a person experiences strong emotions like anger, the body releases adrenaline, which can lead to involuntary muscle contractions, including in the eyelids. Additionally, stress can cause fatigue and strain on the eye muscles, further contributing to the twitching. It's a physical manifestation of the emotional state affecting the nervous system.
