Medical knowledge does not mean you have to study in deep; a knowledge, which is related to your own system, can be regarded as medical knowledge. The people who are already from the medical field does not need to know more because they have already studied about but the non-medical background people are required to have at least the knowledge of basic things which can help them at the time of emergencies.
There is nothing knowledge of which is useless because somewhere or the other in your lifetime it will help you and when it comes to medical field then it is must for everyone. It does not matter whether the other person belongs to the medical field or not because few situations can occur in life anytime so it is necessary for all to have at least the required knowledge so that at the time of need it can help them.
At the time of emergency do you want to look at everybody’s face to come and help and what if people present there has no knowledge about it? You cannot rely on anyone because there are so many people who think they have doctors to help them so what is the need to have knowledge of it.
Nothing comes after knocking your door or after asking so it is better to oneself prepared enough to act sensibly at the time of need because you cannot wait for the ambulance to come and what will happen till then? You cannot avoid serious situations and cannot rely on something because ambulance can also be late and if you have some knowledge about the situation they at least you can handle it until the ambulance comes.
If you will take a survey and ask people do you have some knowledge about medical? Then some will say “I have some knowledge but I will prefer doctor” and some will say, we already have so many qualified doctors then what is the need? They will simply leave your question with a question. But at the time of emergencies or the conditions which can be handled by any common person then people with no knowledge regret of not having even the basic knowledge about it.
You do not have to take classes or something to gain the required knowledge because you can easily search for them on internet as it is a home of every field you can easily know about anything. It is nothing like the information given will be in technical language and you have to use google again and again. There are so many posts which explain the situation in a very simplified way so that even a layman can understand it effectively. Not only the text part but there are so many videos available which are specially made for the people who are not of medical background so that if they are not sure of something then they can look for it in a very simplified way.
