Why sex is binary. Interesting video--only makes a very narrow point. Not about body type variations, not about gender.

I squawked carelessly about this well-produced and informative video. Apologies, @Zaelefty; I misinterpreted your description. Thank you to @sometherapist for bringing this to my attention. Hopefully more people will watch it now, in any case.
