The Physics of the Leaning Tower

An adult head weighs about 5 kg (10–12 lbs). When your head is perfectly upright, your cervical spine supports that 5 kg.

At a 15-degree tilt, the effective weight on your neck muscles and nerves increases to about 12 kg.

At a 60-degree tilt (the typical "phone-scrolling" angle), that weight skyrockets to 27 kg (60 lbs).
