Answer:
The course of basic first-aid will be helpful for me because it prepares me for any kind of medical emergency, I could save lifes with knowing the correct technique.
Explanation:
Every medical emergency in which someone is in real death danger can involves that the patient´s heart stops and he/she stops breathing. On a basic first-aid course the experts teach us what to do in case that happens, in basic words, to keep the person alive until the ambulance arrives to take the person to a hospital.
First aid involves knowing how to cure a simple burnt to having the heart re-animated by using the needed equipment. They teach us how to to a proper CPR in case someone needs it and-more important- how to know when someone needs it.
Also, they prepar us for several emergencies, like choking with food, an allergy episode (how to use the anti-histamine shot), to keep a fracture well until the specialists arrive.
All this information will be helpful for me as a certified trainer because I will be prepared for any situation and most of all, I will be calm.
Does Natural selection or evolution involve with this? it sounds like spiders and other Insects or bugs that have evolved to be able to have limbs in order to survive in a environments that would require extra limbs. probably from genes being passed on and also being mutated positively in order for the newer species to better adapt. the pair of legs could have been increased because of the environment that requires it and also as the mating changes it's basically survival of the fittest.
