To this conclusion I have come: the most deadly years of our lives are the ages of 16 to 21. Those years give us a headiness that comes from new freedom — a driver’s license — and the passing of the torch from strict childhood rules to more trust, different restraints and relaxed curfews.When you add the opportunity to go off to college or move out on your own, we’re fooled into thinking that we’re mature enough and wise enough to make decisions that will affect the rest of our lives.It’s scary.Sometimes I look back and thank God for the grace that got me through those years. And, I thank Him especially that there weren’t cell phones back then that tempted me to text and drive or make calls while steering my way around town or on the interstate.
