Our biology tells us that love is good by activating these reward circuits in our brain, and it tells us that love is painful when, after a fight or a breakup, that neurochemical reward is withdrawn.
A nosa bioloxía dítanos que o amor é bo activando estes circuitos de recompensa nos nosos cerebros, e dinos que o amor é dor cando,  despois dunha pelexa ou ruptura, a recompensa neuroquímica é  a rehabilitación.
