Nature, says Dr. Beamish, is like a small house with two rooms - both living rooms. Many animals move between both rooms. Humans, who move back and forth the most, also live with the highest stress. Whales, on the other hand, unlike humans, live with very low stress. We move back and forth between the two parts of nature and change our stress level.
Altruistic behaviour creates very low stress.
It's like humans who discover love at first sight or sincere love between friends or spouses, he says. People exchange 100 words but they have far more information than those words - they are picking up the feelings. That ability exists between all living organisms. For whales, going up and down through thermal layers is important. For them, some of our senses are not important.
