Life and death

I think everyone is a little scared of death.. I know I am, but being lds I just think of heaven and life after death. But I'm still scare of death because I don't know how I'm going to die, or exactly what's in store for me after I die, and I obviously don't want to leave any one sad after I die.. (Which I probably wouldn't) but I wanna think that people would be sad after my death.. Anyways I just want to live as long as possible.. Yolo right? No, wrong, I want to live the best life I can not the yolo life.
