This is why I always made an effort to absorb as much information as possible. Of course here there is so much more of it that I have to be selective, as I haven't the time to learn everything, but this is also a fair example of how little one knows even when one knows a lot. I take it the combined knowledge of several versions of Earth along with other planets and beings entirely is to blame for how much more you have learned of medicine?
For both personal and ideological reasons, the freedom of being. As I'm sure you know, women as well as people of certain races and ethnicities, creeds and sexualities had various degrees of limitations put upon them with regards to who they could be and what they could do safely (socially as well as legally). All that appears to matter not one bit here for one, and while I know on other Earths it is not so cleanly done and other such issues arise, some progress still appears to have been made over time.
