Pulitzer Prize-winning author Norman Mailer spent five days in a Boston hospital with breathing difficulties.
His editorial assistant Dwayne Raymond Prickett said on September 6 that the 84-year-old author has been told not to travel until cleared by his doctors.
Prickett said Mailer has adult onset asthma and was experiencing "labored" breathing.
