Prey or predator, it is sound advice.
Ever have one of those days? You know one of those days when you get up with all good intentions of doing what needs to be done and you get up and go about it but there is something in the back of your mind, something in the weather, something just outside your peripheral vision that says to you, "Something Is Out There".
So you keep alert just in case, but you weren't alert enough or fast enough even though you could feel that it was there?
Then zoom, whip, zap, bang, dang dang dang, oh shit.......
