Most of us have switched over to the digital world where everything has been digitized. Back in the days like you have said the most common method of cooking was firewood. I am one of those people who did not grow up cooking with firewood, but as i grew up, i learned what my parents grew up with. I actually find firewood much more convenient and faster as compared to gas. first and foremost, it is readily available, very convenient you can put up a fire literally everywhere and you prepare a meal. I learned one thing, food that is cooked with firewood is very tasty. there are certain pots that are used to prepare efferent meals, say for example meat or chicken, when they are prepared in those clay pots they bring out an aroma that is unforgettable, then the taste is just out of this world. In fact right now i am actually salivating when i remember the chicken and meat that grandma used to prepare for us when we visited her out in the country side.
It's funny that i can sit and cook with firewood and not get a headache, as opposed to charcoal. When i use charcoal, i always end up with a headache i have never understood that fact but i still use it because i need to sometimes. I took it upon myself to learn how to cook with firewood because you never know where your going to end up someday. It is crucial to learn this things and techniques because they will one day come in handy and you will be so glad you had the skills. Gas is good and very advantageous to people who live in big cities, because this are people who are always busy with work, so someone doesn't have the time to come home late at night to start lighting a fire so that they can prepare a meal, but in the village all you do is prepare the meals eat when it's nice and hot then go to sleep because there is not much to do there after meals, if you come late, there is a way they preserve the food to keep hot just next to the fire place.
