For me, death is actually more disappointing than scary.
Imagine how many interesting discoveries you'd lose out on after you die, how many useful and curious inventions will just go past by you. What amazing things will we discover in space, that will again and again force humanity to change their fantasy "laws" for the Universe. How we will try to reach out to these discoveries.
And especially, imagine just losing ALL your memories, your experience, your passions, your achievements, to death. All your preferences and all you've gathered along the way of live is just gone.
It'll be so fucking disappointing to die.
, at least try to live on. "You always have a chance as long as you're alive" is my motto for that case, maybe try to adopt it too?
