In the early nineteenth century, Shakespeare was the most widely performed playwright in both the North and Southeast. In the first half of the nineteenth century, English and American actors could always earn money by performing Shakespeare in towns both big and small. American audiences were famous for their participation in performances of Shakespeare's plays: They hurled eggs and tomatoes at the villains and cheered and whistled for the heroes. By the end of the nineteenth century, theater owners claimed that most ordinary people couldn't understand Shakespeare, and they were refusing to stage his plays. In the early 1800s, theater goers in big cities could often choose between three different productions of Macbeth or Romeo and Juliet; by the end of the nineteenth century, it was hard to find production of a Shakespeare play, let alone several. a. Early American audiences embraced Shakespeare's plays enthusiastically because they wanted to prove that they were as clever and sophisticated as their former British rulers. b. The role of Shakespeare in America changed dramatically as the nineteenth century drew to a close.

It's extremely important. We have 60 years of research showing us that. But sedentary behavior is also important. . . . If you exercis for 30 minutes a day.
