A person's personality and behavior are influenced by many factors, including heredity, environment, education, social interaction and so on. So you can't simply connect the size of your chest with your temper.
In addition, women's chest size is influenced by many factors, such as weight, height and body fat rate. These factors are not directly related to personal emotions and behaviors.
Therefore, it is impossible to determine whether there is a direct relationship between chest size and temper.
