#4 – Chromosome X

Another possible explanation for women’s longevity (and for many other differences between men and women) is the fact that they have two chromosomes X, while men only have one. There are structures in our RNA (Ribonucleic acid), which practically tell genes what to do; they play a fundamental role in the immune system’s capacity of removing infections and diseases. Most of these structures are found in chromosome X. Thus, it can be said that women are programmed to be healthier and live longer than men.
