Wow. I'm sorry to hear that. Anyways, about 15 years ago, when I'm flying to Orlando to work outstations, there was a young girl sitting next to my seat. At one moment, when she breathed out, it smelled so horrible I almost threw up. As I recalled, it smelled like the mixture of rotten eggs and vinegar which might already be resting in her mouth for years. 15 years later, and the memory is still clear.
