Death is always scary. It is enough to make me sweat cold to even just think about it.
I think the scariest way to die is to die with unfulfilled wishes. It is the most unready, unwilling and regrettable form of death.
The sad news is, we never know when we will die. That is why we are never ready.
However, I do know one way to die less scary. That is to live today to the fullest and feel no regret about it.
