I'm sorry to burst everyone's bubble but this doesn't make sense. The average person is not pregnant. Therefore the average person does not have more than one skeleton in their body.
It's the average amount, meaning that if one person out of the entire world was pregnant, the average would be technically more than one, even in the slightest degree.
I think even on balance, considering fractions of skeletons in whole people, you're going to end up with more than one skeleton per person despite some of those people missing bones or limbs.
It's like one sixth of a percent more than 1:1 if there are 135 million babies born each year on earth, but that's not nothing.
Yeah that's kinda the point I was getting at. With a baseline of 1 and the 100% probability of 1 person out of 8 billion being pregnant, it will always technically be more than 1.
