I strongly think that stress is the most important thing scientists should find a cure for. Needless to say, good stress give a motivation to us to do something good. However, bad stress make us be sick in many ways.
Firstly, we feel psychological pressure from stress. It make us have a depression or anxiety. If this symptom is getting worse, our mental health also gets worse.
Secondly, stress affects physical health such as the blood pressure, the digestive apparatus, and the breathing problem.
Finally, stress degrades the immune system.If the immune system is degraded, we can get a disease easily such as cancer.
We can get a toothache, hair loss and bad breath due to several reasons.
Toothache from cavities and inflammation of the teeth nerves are the most common. We can get a hair loss just not only because of the stress, but also because of the genetic effects. There are many reasons of bad breath such as the heart disease , the lung disease, poverty of blood, obesity...etc.
To sum up, I strongly think the stress is the most important thing that scientists should find a cure for. Furthermore, toothache is the least important of these.
