Oh, that's a definite twinge. Take a breath. It's not pain, it's like a missed beat, and then a bubble, something like a bubble in my chest, hollow and tense. It must be stress-related. It's gone now. It was there when I breathed in. Take a breath. It's okay again, it's gone now. It was just a twinge. I wouldn't even notice it if I wasn't on the lookout, checking myself for symptoms.

Old age needn't be all that bad. That old man with the goatee beard and the dog... he seemed pretty cheerful. It can be okay. Live life your own way. Take pleasure in small things. That's the secret. But you need good luck with your health.
