This is kind of the nature-nuture thing revisited. We are born with bodies that are very similar to other human bodies. Nevertheless, females are born with different reproductive systems from those of males. Within elements we share, we each have individual differences: our unique talents and weaknesses. The basis of all these things last for life, but our unique skills and failings can be improved or weakened to some extent by our experiences, choices, and individual efforts. And these will in turn impact on society and its arrangements such as those of our health system, which is a present under immense stress.
