Ladyjus you gave me a laugh, with all your mishaps. I did judo for 8 years, ending up teaching it, and never had anything worse than a bruise.
My only water-connected injury was when we took our Guides on a canal barge for a few days. I jumped onto the towpath, my foot went down a hole which was hidden in the grass, and I tore my calf ligaments. It was about a year before I fully recovered.
As for swimming, my common sense says, “Do this, this and this, and you will swim perfectly well.” All my instincts, though, scream,”You’re going to drown!” I was pushed into the diving pool, as a child, and it really broke my nerve. I have had three courses of lessons, and several one-to-one sessions, and have finally decided, at the age of 81, that I will never make a swimmer. Such a shame, as my Aussie kids all have pools, and I feel such a lemon, sitting out, but heigh-ho, it’s not the end of the world!
