Your "immune resilience" greatly impacts your health and lifespan

> People with high levels of immune resilience live longer, resist diseases, and are more likely to survive diseases when they do develop.

Pardon me, but isn't that stating the obvious? I mean tto say, your immune system protects you, and the better it does the less likely you are to succumb to disease, is what the immune system does. It's not like you're nervous system is going to beat back an infection.
