What causes the discs in the neck to be paper thin?

The discs in the neck can become paper thin due to a combination of factors, including aging, wear and tear from repetitive movement, and injury. As we age, the discs lose water content and elasticity, leading to degeneration. Additionally, conditions like herniation or degenerative disc disease can contribute to the thinning of these discs. Poor posture and lifestyle factors, such as lack of exercise, can also accelerate the deterioration of spinal discs.
