Your mother claims that she has found a wonderful new treatment for her arthritis. she read "somewhere" that rubbing vinegar into the affected area for 10 minutes twice a day would help. she tried this and is convinced that her arthritis has been lessened. she now thinks that the medical community should recommend this treatment. what alternative explanation(s) might you offer to your mother for why she feels better? how would you explain to her that her evidence is not sufficient for the medical/ scientific community?
