Perhaps some reader has his favourite, easy-to-exploit security hole he'd like to share? :-)
Ouch, and I now know that horse can kick you when you are still on the ground, holding reins. She hit a belly, and it hurt quite a lot. Fortunately she did not seem to make too much damage (but that took doctors 2 hours to figure out, and they had their "this si serious" looks). For some reason the kick seems to have increased gas production in the intestines...?
