I don't want to tell the guy not to get a new helmet, its his head, and you just don't know.
That was my point for telling my story...no outward visible damage, not even a scuff or scratch. ('m assuming my head hit something soft enough along the shoulder of the road that protected it's shell but, it still absorbed the impact from within from my skull)
The surprise I had when I tore down that old helmet years later was NOT a good one but, better than being surprised had my head impacted something between the last accident and when I threw it out.
F.W.I.W. it was a Shoei RF model. (900 series from what I remember)
