In Diana Gabaldon's "Written in My Own Heart's Blood," it is highlighted that while many individuals may experience irritability when they are hungry, a person with red hair can react dramatically differently. This commentary suggests that redheaded individuals may have a heightened sensitivity to hunger that can lead to explosive outbursts, painting them as particularly volatile when faced with an empty stomach.

This observation emphasizes the unique temperament often associated with red-haired people, suggesting that their emotional responses may be more extreme compared to others. It invites readers to consider how physical traits, such as hair color, might influence personality traits or behavioral responses in social situations, particularly when it comes to basic human needs like hunger.
