I have to wonder - what is staring at our phones all day doing to our necks? And are we going to have an epidemic of debilitating cervical spine issues pop up 10 or 20 years from now?
I frequently see children bend their necks at a full 90 degrees to stare mindlessly at an iPad rested on their laps. I would not be surprised if they grow up to have spinal issues. Parents don’t seem to care.
Likely something similar to staring at artwork all day... or paperwork, a book, badly-positioned television. Or a car engine (especially if you generally do work from above instead of below). Or anything else you look down at for hours at a time.
