Whats the Problem? Life is life, death is death, 10 year olds know that for true. Everyone should learn about great losses and fear, so they can cope with it later in life.

Life is not a nice soft bubble, and kids should not life in some kind of concrete bunker erected by their "caring" parents - which includes sex ed!
