Also, I think having a positive attitude each day, learning how to "breathe" (we forget sometimes!) thru those super stressful moments, much plant-based diet like you said, healthy supplements (as opposed to meds if you can), yoga/exercise, letting go of anger, prayer and lots of GRATITUDE for every moment and challenge! I also drink at least 1 tsp. of apple cider vinegar a day w/water. I haven't had a cold in a few years!
