You are the exception to the norm — one tough bird.
With others the spirit is willing but the flesh is weak.
Nonsense. Pneumonia is like pin the tail on the donkey. You could react any of many ways.
Many people only are affected by it like a flu. Same happened with my husband. He’s much younger, but it was like a tiring flu for weeks, mostly before he was diagnosed and cared for. He took some time off after the DX, and had taken a few days before when he got a slight fever and we really thought it was a flu that was getting better.
My dad, at least that age, has had several bouts of walking pneumonia. He was just run down. He was fine once DX and RX.
