🐄 The Science
University of Northampton study (2011):
- Cows paired with best friends vs. strangers
- Measured heart rate and cortisol (stress hormone)
Results:
- With best friend: Lower heart rate, less stress
- With stranger: Higher heart rate, elevated cortisol
- Separated from friend: Significant distress
