Bending the neck at 60-70 degrees is akin to carrying a wt of 25 kg on your neck. This can put enormous strain on your neck muscles and lead to premature wear and tear of the supporting structures
This can result in significant disability and pain
So, keep and maintain your neck at eye level
Avoid texting and encourage voice calls to avoid poor posturing
Take regular breaks from mobile phones and perform gentle neck and shoulder exercises.
