There's no point in fearing death. Death will come when it's time. It useless to worry since any number of unlikely scenarios could occur at any given moment. A sinkhole can form under you. Debris from a plane could hit you. You might just choke on nothing.
What you need to remember, is that you are basically unkillable until it's your time to die. Doing something stupid that results in your death, may however be exactly how it was meant to be.
