You probably already know that people who are more conscientious (responsible, organized and capable of self-control), tend to live longer and have a 40% decreased risk of death compared to the less conscientious people. But why that is that and how that happens was not clear … until now.

A recent international study investigated the way our personality is linked to the risk of death and found out that our immune system is responsible for that. Specifically, more conscientious people live longer due to lower levels of interleukin-6, which is responsible for 18% of decreased risk of death. Interleukin-6 is an important part of the immune system that is not only involved in inflammation and dealing with infection but also in regulating of metabolic, regenerative, and neural processes.

The researchers believe that there are possibly more biological ways that explain why our personalities can play a significant role in our longevity.
