I have been pushing "Invisible Women: Exposing Data Bias in a World Designed for Men" quite a bit recently. It looks at a whole mass of issues where women are overlooked in very fundamental ways, largely because the relevant information is not collected, or when it is, taken into account. I am sure it can open your eyes to issues whoever you are, but especially so for men.

To take a simple example: why is there no suitable seatbelt for pregnant women?
