I actually almost died to this thing. I have pretty poor health, and I have heart attacks every 1.5~2 years. And once I was in different city, and there happened attack. Doctor was young doctor, and he was trying to do things he usually do, but they were not helping, and he was not sure why. Good that I was not alone there and my friend insisted on getting doctor from other clinic as fast as possible. And that other doctor actually helped me. And it is all because heart and veins are placed a bit differently, body is a bit different, and hormones (like progesterone, which transwomen are not taking) have influence on how heart attacks are different in women bodies. And that young doctor was only managing men before, and in university he was only studying on male patients, so he did not knew about differences at all. And it was eye openner to him. I hope he became more capable specialist after that and learned differences in sexes biology.

So this transwomen cry about "why book is not about us too?" is disgusting and can cost lifes. Why they even bother, their male body is already very studied, and if I was transwoman - that young doctor would cure me no time, because "estrogen pills" are not changing any physiology at all, only growing some extra fats around their body. Their habbits are still staying men habbits as well. So book is in no way about them or should touch them at all. It is same as trasnwomen will come to nuclear physicist and ask them to study carbon chemistry too, or they are transphobic.
