When we look at life and death from a broader perspective, then dyhing is just like changing our clothes! When this body becomes old and useless, we die and take on a new body, which is fresh, healthy and full of engery! This need not be so bad!
Pippin: I didn't think it would end this way.
Gandalf: End? No, it doesn't end here. Death is just another path . . . one which we must all take. The grey rain-curtain of this world rolls back, and all change to silver glans...
Gandalf: ...And then you see it.
Pippin: What, Gandalf? See what?
Gandalf: White shores . . . and beyond. A far green country, under a swift sunrise.
Pippin: Well, that isn't so bad.
Gandalf: [Softly:] No... No it isn't.
