Why is it that women are stronger than men?

We have two X chromosomes

Of course we do – that’s what makes us female. But it also makes us brilliant at fighting off bugs and potentially protects us against cancer. Dr Claude Libert found that the X chromosome contains 10% of the gene-controlling substances called micro-RNAs in our system. These are important in overall immunity but also in the body’s ability to fight cancer. Simply having two of these gives us a major biological advantage over men.
