One day, the organs decided to hold a meeting to determine who should be boss.
The brain said, “I have the capacity for abstract thought, and I also control the autonomic processes of the body. Clearly, I should be boss.”
The heart said, “I pump the blood, taking oxygen to all the parts of the body. Brain, without oxygen you die before anyone else. Clearly, I should be boss.”
The stomach said, “Without me, none of you could function. I process food and convert it into the energy you all require. Heart, without energy you stop pumping. Brain, you consume energy even when the body sleeps. Clearly, I should be boss.”
The sphincter said nothing, and remained closed. After a couple of days, the brain had a headache, the blood was toxic, and the stomach was bloated. The brain, heart, and stomach unanimously declared the sphincter boss.
