I take a first aid exam once a year.
Last time, no one from the group of 10 people was able to save Goshu-trainer. He had his lungs broken, his neck broken, his keys broken, his ribs broken more than the person has at all, in general, did not let Goche get bored.
A very useful practice, I began to behave much more cautiously, because neither an ambulance to wait, nor even an easy death to die, I will not be given here.
