Either really dramatically or really peacefully/touching. Or a combo of both would be nice. For example something dramatic yet touching like jumping in front of a bullet for someone I really care about and then peacefully like them holding my hand in my last moments. It's pretty cliche, but in my mind I make it really cute/sad. It's a MASTERPIECE DEATH.
Or really violently, but yet dramatic and touching in a really upsetting way. Such as someone I really care about is tied up and the only way to get to them is to cross a fairly large field and so I start to run towards them and as I do bullets start firing, but as they start to enter my body it goes into slow motion and you hear the person I'm running towards yell "Nooo!" really dramatically and my body moves back in forth from the force of the bullets.
Yeahhhhhhhh I just think sacrafice deaths are the best + I really like movies and I know I wouldn't be satisfied unless my death was really touching or dramatic or COMBINATION. As for when I don't really know, but dying doesn't bother me so I wouldn't want to live to the point where I can't do anything myself or I start to go senile. If I'm going to have a fairly decent life then I'd like to live it up to the point where I start to lose it. Otherwise count me out now if it's going to be absolutley horrible.
