What Causes Runner's High?

An emerging field of neuroscience indicates that the endocannabinoid system may be more responsible for feelings of euphoria after exercise than endorphins.

For decades, endorphins have hogged the credit for producing "runner's high," that fleeting sense of euphoria and calm that many people report experiencing after prolonged exercise. Who among us, after an especially satisfying workout, hasn't thought, "ah, my endorphins are kicking in." Endorphins are the world’s sole celebrity peptide. ... Finding endorphins in the bloodstream after exercise could not, however, constitute proof that the substance was having an effect on the mind. So researchers started to look for other candidates to help explain runner’s high.

How pharmaceutical companies game the patent system

When these companies compete, in the current system, the people lose.

Top Video Splash
  • When a company reaches the top of the ladder, they typically kick it away so that others cannot climb up on it. The aim? So that another company can't compete.
  • When this happens in the pharmaceutical world, certain companies stay at the top of the ladder, through broadly-protected patents, at the cost of everyday people benefitting from increased competition.
  • Since companies have worked out how to legally game the system, Amin argues we need to get rid of this "one size fits all" system, which treats product innovation — "tweaks" — the same as product invention.
