People have evolved to withstand falls on the level and collisions at running speed. If you want to go faster / higher than that you must be able to assess risk and control it to an acceptable level.
Trouble is that most people can't assess risk accurately and resort to all sorts of approaches which make them feel safe (including for example lucky pebbles).
So assess the risk of flying (and anything else for that matter) then either accept it or don't do it.
It was understanding and accepting the risks that got man to the moon. Safety is an enabler and if it is ever not an enabler then it is a weak excuse for something else like fear of litigation or cost avoidance.
