Excerpt from Chapter 2 By the time he was thirty-five, Cornaro was severely ill. In the following years, he grew so sick that physicians were regarding him as terminal. Because of poor nutrition and exhaustion, Cornaro was suffering from chronic fevers, insomnia, gout, and violent colics. In his writings, he is describing his constant pain as "a condition worse than death." Cornaro had consulted two doctors in Venice and received contradictory advice. One doctor had told him to eat more meat and drink more milk; the other had advised Cornaro to eat more vegetables and fish, work fewer hours, and take a nap during the day. After listening to the physicians, Cornaro had felt more confused than before. Excerpt from Chapter 3 Mendel's dream had been to become a school teacher, but he failed the oral examinations in 1850 and 1856. He possessed more than sufficient knowledge to become a school teacher, but due to his shyness, he had been virtually paralysed during the oral examinations. As a result, he never got a teacher's certification. After the massive efforts he had invested in his studies, the disappointment of not being able to become a teacher marked Mendel for rest of his life. His failure to pass the teacher's examinations meant that he would never be able to get the job he wanted. When he faced the fact that he would never be able to achieve his goal, Mendel came to accept that he would be spending the rest of his life in a monastery.
