Synchronized exercise and endorphin release

Recent research published in Biology Letters suggests physiological mood systems may have been involved in the evolution of coordinated physical activities. Researchers from the United Kingdom discovered that the pain threshold of collegiate rowers significantly increased when exercising with teammates v. solo-exercise controls 1. This increase in pain threshold was also observed for individuals exercising [...]

They discovered that Nazca booby hatchlings have higher perinatal androgen [...]
