The first question's answer did not have to be about music, it could have been anything that helps you remember things. I remember as a child having to learn the colors of the rainbow in school, as part of our Science class about light. The teacher told us to think of a boy named ROY G. BIV — Red Orange Yellow Green Blue Indigo Violet — and we ever forgot the colors in the correct order! 😁

Ginger is, indeed, good for healing! Also, eating garlic and onions will boost one's immune system, too, and they are both very tasty! That is excellent that your friend taught you those things, what a good friend to have! 😊
