How do you die of shark attack!?

I'm not worried about my unlucky trait, from my experience if your sim has the unlucky trait it increases the risk of death. I know you can't actually die of anything ,but old age with it, BUT if you change your unlucky trait with testingcheats as the sim is dying it will die. Yet, that is besides the point a ghost will still appear with the unlucky trait, but the Grimm Reaper wont let you stay a ghost. I want to physically see my sim die from shark attack not so much kill it. I bought each meat and fish item from the store x 12 and put it in my sims inventory. I edited the diving lot and made it flat, deleted everything but spawners and added LOADS more shark spawners. Every time my sims diving skill gets too high I start over. Whenever a shark does attack I use testing cheats to lower her energy so she cant fight back as well. Diving is each sims only skill, for each sim I try. My sims I use are young adult humans. Please help, Im still trying to do this! I even tried making an evil mermaid in my household to summon sharks to kill her fellow household members (not herself). Nothing is working.
