Ways to kill the Sims 2

Apparently there are 9 ways to kill your Sims in Sims 2, I can only figure out 8 though. I'll post the 8 and try and figure out 1the 9th.

1. Drowning
2. Fire
3. Starvation
4. Depression (if you don't let them go to work/school and do nothing to improve mood)
5. Viral infection (from the hamster if you don't bathe them)
6. Killer plant
7. Fireworks in the house (works good with lots of rugs on the ground)
8. Exhaustion (if you don't let them sleep)
9. Electrocution (if you have them change lightbulbs in cheap lights)

K now I know that is 9 but I don't know if starvation/exhaustion/depression are the same death, if they are then I only have 7 and if they aren't then I have all 9 WooHoo!!
