Hi, recently on the past July 4 holiday I went swimming with my family in a nearby river.  There were a few rope swings which were tied to trees on the bank.  One of them was very tall, I'd say 20-30 ft drop.  A few other folks were swinging from the tallest swing and since they emerged from the water ok, I thought I'd give it a try.  It was fun, on my third try, however, I let go of the rope over a 'shallow spot' that, best as I can describe, appeared out of nowhere.  I remember a feeling (I say 'feeling' because I'm not sure the thought was necessarily verbalized in my head) that the water beneath me parted a bit before I hit.  I mean, the whole thing was so strange.  Anyway, I received a major sprain to my ankle.  No bones were broken, even though when I described what happened to the doctor he told me it was the equivalent of me jumping off of a three-story building.  My heel and ankle were damaged very badly, My whole foot, except for the very top, was literally black and blue but mostly black.  I am still recovering, with the aid of a walking boot now.  Your article made me wonder.  I thought of Genesis 3:15, "And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel."  Thanks, God bless all of the doves, in Jesus' Name,  Sarah
