A pious man who had reached the age of 105 suddenly stopped going to synagogue. Alarmed by the old fellow's absence after so many years of faithful attendance the Rabbi went to see him.
He found him in excellent health, so the Rabbi asked, "How come after all these years we don't see you at services anymore?"
The old man looked around and lowered his voice. "I'll tell you, Rabbi," he whispered. "When I got to be 90, I expected God to take me any day. But then I got to be 95, then 100, then 105. So I figured that God is very busy and must've forgotten about me, and I don't want to remind Him!"

Thomas Hunt Morgan

Born 25 Sep 1866; died 4 Dec 1945 at age 79. American geneticist and zoologist famous for his experimental research with the fruit fly by which he established the chromosome theory of heredity. He discovered that a number of genetic variations were inherited together and that this was because their controlling genes occurred on the same chromosome. At Columbia University (1904-28), he began his revolutionary genetic investigations of the fruit fly Drosophila melanogaster (1908). Initially skeptical of Gregor Mendel's research, Morgan performed rigorous experiments which demonstrated that genes were linked in a series on chromosomes and are responsible for identifiable, hereditary traits. In 1910 he discovered sex-linkage in Drosophila, and postulated a connection between eye color in fruit flies and human color blindness. His study of the characteristics inherited by mutants ultimately enabled him to determine the precise behaviour and exact localization of genes. Morgan and his "fly room" colleagues, mapped the relative positions of genes on Drosophila chromosomes. Morgan published his seminal book, The Mechanisms of Mendelian Heredity in 1915. Though this work was not widely accepted initially, Morgan was awarded a Nobel Prize for physiology or medicine in 1933.
