Coughing in the theater is not a respiratory ailment. It is a criticism.
Whooping cough is not a mild disease. Whooping cough, before the vaccination, could make you very, very sick. First of all, there was a chance you could die from it - small chance, not a big chance. You would be coughing and coughing. It wouldn't last for a few days, like a cold.
My mother was a nurse, and in her era, most diseases weren't understood; people put mustard plasters on knees and rubbed camphor on your chest if you had a cough and did funny things to you if you had tuberculosis - all these things that really made very little difference once proper treatments were brought in.
Christian Scientists not only don't like to acknowledge illness; they don't like to see it. On occasion, I was sent to my room from the dinner table for sneezing or coughing; I now know that I was allergic to our cat.
When my husband turned 40, I was obsessed. 'Has he had his medical checkup?' He needed to go to the doctor; he needed to go to the dentist. Any little cough, I was really on him. Then he turned 40, and I thought, 'Maybe that's why I've been so obsessed with his health!'
The worst moment was when I was performing and I was about to sing, but I choked. I had a tickle in my throat and I started coughing, and I couldn't get the words out. It lasted for like thirty seconds, but I got over it, and luckily the crowd didn't seem to care.
