What do you suggest if my husband lung collapsed 14 years ago. he seems to think he can't ride rollercoasters anymore because of it. is this true?

Possibly: Primary spontaneous pneumothorax (PSP), air around lung in pleural space, no precipitating event in a person who does not have known lung disease and causes lung collapse. Spontaneous pneumothorax, increased risk (32%)for another collapsed lung in future. Some say prevention of pneumothorax includes: avoiding exposure to high altitudes, scuba diving, flying unpressurized aircraft and stop smoking
