When we are older and already have a salary, we can take on food additions that we did not have before and can lead to overweight, which we have no experience of.
Changing eating habits that we did not have before can lead to a scare. How?
Eating more fats increases the level of cholesterol, which can clog our arteries and this effect can cause a stroke. A huge scare.
When we suffer this scare, our body can react, producing twice as many neurotransmitters, which will help digest these fats, but can lead to a risk of mental illness.
Double the number of neurotransmitters can be an extra workload for the neurons, which involves a lot of energy expenditure from their proteins, so that the organs make an extra effort to metabolize the fats and this can be a symptom of stress or mental illness.
An example of what it leads to, with more neurotransmitters, is the loss of sleep, so that we do more exercise and can reduce fat or bad dreams and a lot of stress, which leads us to more physical movement or exercise.
Another example is that it can give us heart palpitations to stay awake.
