Yesterday morning I was enjoying my usual walk along a trail that runs beside the harbour, when a woman coming in the other direction stopped and said I looked healthy. I laughed and said I wasn't, it was all due to medication. She replied, saying as she had approached me she had "seen sickness" but as she got closer she thought, no I was all right! I thanked her, said I did what I could, and we went on our respective ways. I wish I had asked her how she knew. When I walk along that particular stretch I feel the air is particularly fresh and have got into the habit of "breathing in health" and "breathing out toxins"!
