To turn the general ideas of the previous chapter into specifics, this chapter takes a fanciful look at the hidden symphony to see what happens in Usain Bolt’s stress response system during his ten-second sprint as the world’s fastest human. He is one of the master conductors of the stress response system, with his speed as proof of his prowess. An appreciation of the orchestration required to mount this everyday miracle provides the background for understanding the way persistent and severe stressors disturb this process. The anatomy of six major organs in the stress response system is described and depicted.
