Answer to Question 2
Researchers have defined creativity as the ability to produce work that is novel, high in demand, and task appropriate. The number of creative ideas one has varies across the life span. Research indicates the number of creative contributions a person makes increases through the 30s, peaks in the early 40s, and declines thereafter.
People do not stop being creative, rather, they just produce fewer creative ideas. In fact, the average age at which people have made substantial creative contributions to society, such as conducting research that resulted in winning the Nobel Prize, increased across the 20th century.
