What texting does to the spine

A new study suggests that looking down at a cell phone is the equivalent of placing a 60-pound weight on one's neck.

I've always wondered about that (the texting, that is...). You see people standing or walking and looking like they have advanced osteoporosis. It's scary.

How is that as compared to the same posture reading a book for hours on end?

Watch people who read a book: they tend to hold books at a more comfortable distance than is typical for smartphones because it's far easier to read a book at distance given the constant font size and the flow. Pages and apps on smart phones often have varying font sizes, images and a general blockiness (instead of constant left, right, top to bottom flow). It means you need to focus more and actually read instead of being able to easily scan.

The weight of your head doesn't change meaningfully based on its position; the net force on the spine does. The actual study linked to got it right; but whoever wrote it up for The Atlantic managed to screw it up despite the illustration they cropped for their picture explicitly stating that it was the force applied to the spine not the weight of the head. :doh: I'd be interested in seeing more details of the model itself; the numbers they're reporting are ramping a lot faster than my half-remember freshman physics suggests they should. The discrepancy is not particularly surprising because of how complicated the real spine is vs a trivial force diagram, but I'd still like to understand how/why it's different in more detail.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason? Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful? --Zachris Topelius Training a telescope on one’s own belly button will only reveal lint.

Sadly, most people don't read.
