  Hello Pravi! Living a longer life, in my opinion, not only depends on in the immune system, there are diseases, like cardiac diseases where the immune system can’t do much against them and depend mostly in genetic factors and lifestyle. But, in general a preson with a strong immune system will live a life with less infections and diseases. Cheers!!
