Death and Danger in The Sims 4!

I would like unnatural deaths to be easier, though I don't want them to be really common either. Realistically most people do die when they're old, but then some don't and it seems even when my sims have accidents like getting electrocuted, they're fine and there's an obvious warning that it's fine now but if I make them fix something again they'll die. And I don't have the heart to make them do that so I just let them go, but it'd be cool if it did happen every now and again on it's own.
