Once my dad was very sick and he was running a temperature of 104. Me and my brother were sitting on the two sides of his bed worried about him. He asked us why we were having so sad faces. when we told him that we were worried for him he said that his sickness was nothing in front of his willpower. Then, he asked us to hold his hand and he closed his eyes and took a few deep breaths. he were surprised to feel his body temperature going down. we checked using the thermometer and it now read 101 degrees. we were so happy and yet so astonished how he could do things likes that!
