Yes - so true about Peter's fear and so well put. He doesn't have the age or experience to calculate risk and realise that while some activities have an inherent small risk which you accept if you do that activity - e.g. riding, sailing; other activities are very dangerous and no sensible person would do them knowing the risk - walking close to very high seas in a storm. And that having the common sense to avoid danger is not the same as being a coward.
