The pic­ture below was used in a case study on stress lev­els at St. Mary’s Hos­pi­tal. Look at both dol­phins jump­ing out of the water. The dol­phins are essen­tially iden­ti­cal. A closely mon­i­tored, sci­en­tific study revealed that, in spite of the fact that the dol­phins are so sim­i­lar, a per­son under stress would find many dif­fer­ences between the two dol­phins. The more dif­fer­ences a per­son finds between the dol­phins, the more stress that per­son is experiencing.
