Video is interesting. I know a lot of people who don't take breakfast and smoke. Most of them have headaches during day, maybe it's connected somehow or maybe not. I also have a friends who started a new healthy life after he decided to buy property in Italy https://tranio.com/italy/ and it helped him. Now he goes for a run every morning, started to eat more healthy food and changed the circle of people around him. So maybe the video is right and you will feel better if you get rid of bad habits.
