St. John's ambulance

I have been taking this course on first aid and CPR training for the past two days:)and I am a certified first aider now;)St. John's ambulance training center, gave this course for whoever is interested at my company. Some of the facts that she was teaching,was very interesting. For instance if your brain lack oxygen for 4 min, you will die!!and other interesting little known facts, ofcourse the difference between sciences like biology and math is that you may have patient that may stay alive after 4 mins, but mathematically it would be impossible..!!!I mean you can prove it later on, with different biological pathways in the body but may consider strage at first, my point is that its not black and white or binary,zero and one;)..anyways, we all had Manikins and we practiced on them. One interesting thing in CPR is that most of the people think that you give CPR to someone who is not just breathing, but that is not true. CPR is given when someone is dead, or basically there is no blood circulation anymore, so you act as their heart and lungs for them. I don't know if I can really do it on real human being though;)although our teacher told us its okay to break ribs;)you are saving someone's life so it can't get worse than his/her death!!!anyways after that we are going to get a certificate and will have $1000000 insurance liability:)!!my proffesional value has increase in two day;)..one funny thing that happened during the course was that everyone gets to practice with their partners, now my partner and I were practicing the initial movements of the body after it has gone to shock or unconscious, and the teacher chose us to do it in the middle of the class!!!and guess who was on the ground;)ofcourse it was me...so my partner did the first aid steps on me and all of a sudden I saw this flash!!!Oh noooooooo..the HR lady took a picture of me and my partner!!it will be published in the next companies newsletter!!!I think the next thing I like to do which I didn't get to do here in Highschool is get my self defence training.
