Theophilus

It's not a matter of age. It is a matter of belief and commitment to God. Without true belief and commitment (faith) reading the bible at any age is a waste of time at best and at worst the foundation of herecy and the basis of the ungodly attacks upon the faith.
The publishing of God's holy word for the public is most likely one of the most greavous sins mankind has ever commited.
Man has taken that which is holy and sacred and reduced to a common bottom self offering at Walmart. Along side home improvement and self help books it means nothing more than another intelectual or entertaining option even to many professing Christians.

The bible in it's whole form is not a child's play thing. While many of its accounts and precepts can be of value when taught to children as stories, much of it requires a maturity and understanding of principles, precepts and accounts of life that are far beyond that of pre teens.

It is the age of accountabiblity and there after when if a person feels the personal need to that they should begin to read and study the scriptures in ernest.

Sincerely
in His word
