They detect differences in gene expression of immune cells of a person related to the degree of extroverted and conscientious person.

In other words, the extrovert, tend to more exposure to infections by nature sociable, close to the outside of them, have developed immune system is capable of dealing with the infection more effectively.

Meanwhile, the individual may be less exposed to more infections due to the cautious, thoughtful and conscientious of them, the immune system possesses less reactive, "Professor Kavita Vedhara, the led the study, explained.
