I rear ended a van while riding a motorcycle, at about 25 mph. I basically belly flopped on the rear roof corner folding at the Saint Barry shirtmore or less. No abdominal bruising at all. 2 years later hopping off the bed of a low truck, I suffered an inguinal hernia and my intestine fell into my scrotum. No bruising doesn’t mean no damage. I had to eat a worm omelette when on a survival course in the Scottish highlands. You make a weak soap solution with washing up liquid and pour it on 1 square yard of the ground. This will bring all the worms to the surface. Drop them in some water to clean the soap off and make an omelette with them as the meat. Instant protein hit and I have certainly eaten worse. The thing is not to think about what you are eating.
