I wouldn't wish a cold on anyone, given that when you have the flu, your body hardly responds and it's hard to get moving. I'm not surprised that you don't want to walk or only take a short walk.
What a great idea to fight the cold with foods full of spices, it's the first time I've read something similar.
It's incredible that your daughter can like spicy foods, she is very brave to do so.
Thank you very much dear friend @sketch.and.jam for sharing this experience, I hope that when you read this comment, you are in better health
