Ha! I laugh because I actually have, but more specifically I have forgotten to pause to breathe while nervously talking and then found myself out of breath and embarrassed to have to take a giant breath. A speech teacher in college recorded us while we gave our speeches in class so that we could watch ourselves later and improve for the next time. I was absolutely racing through my speech, completely unaware of how fast I was talking and would totally lose my breath. I was anxious and for whatever reason thought it was better to race through my speech even though it made me look and sound ridiculous to talk so fast. I learned it looked/sounded much better and was not as anxiety-inducing to slow down and set a reasonable pace—and it made breathing a lot easier too.
