Comment on Our dancers have infinite curves

  Generally, biologically speaking:

  Men have a urethra and an anus.

  Women have a urethra, and anus, and a vagina.

  Presumably, discounting mutations, birth defects, serious injuries, etc, most people have the same number of uh… head/face holes.

  …

  Allowing for rarer cases:

  Also… intersex people exist… there have been at least a few recorded instances of duplicate and/or forking dongs…

  And I guess we could also consider varying kinds of conjoined twins.

  …

  Also also, we could argue about whether milk producing mammaries constitute a topological ‘hole’.

    Vaginas, milk ducts, pores, etc in a topological sense, are not holes, just dents, like the recepticle part of a cup with a handle.

    I mentioned noses and ears before deleting them, because the ENT region is really complicated for a non topologist/biologist to be able to tell if they can be interpreted as holes or not. Luckily for me in this discussion the system is identical for men and women.

      Derp.

      Looks like I need to complexify the manifolds of my brain, haha!

    I think their point was that the hole has to go all the way though for it to count topologically

    The vagina ends at the uterus, and milk ducts don’t go all the way through either

      100% correct, thank you.

        Urethra doesn’t go anywhere either except for bladder, then nephrons (kidneys)…

        Something similar applies to ears, right? And nose… But,

        Also, what about the pores in my skin? :O
