Interesting thought...I am thinking that these words fighting/battling are being used to mean battling with the disease by attacking it with medicines or procedures, or making changes just so a sick person will eventually get better. And the healing process, that's probably what you call it metamorphosis because the person feels better than when he/she was ill. 🤔😊 Just a thought... maybe because I think that sickness and diseases are enemies. ✌🙂
I think a lot of people agree with you.
❤ have a wonderful weekend! ☕🌞
