So my 17 year old sister was driving me and my 13 year old sister from school and my 13 year old sister asked, "Why do we ice our injuries?" And my 17 year old sis said, "Cuase the blood goes to the cold areas to warm it," and I'm like, "But then wouldn't it just bleed more if the blood went to it?" And she's like, "No, they heal the injury," but then my 13 year old sister is like, "How do they know when to heal the injury?" And my 17 year old sisiter is like, "Well they go to the injury and are like 'OH MY GOSH ITS AN INJURY WE HAVE TO HEAL IT!!!!'" and so we all laugh but then Im like, "How does the blood heal the injury" and my sisi is like, "Well they go to the injury and use their magic healing powers." -_-
