How Do You Spend Your Satisfaction Points?

Depends on the sim for I tend to pick traits based on how I picture their character, not just because I have enough points to buy whatever. However, I have never gotten the ones that completely eliminate needs. Those don't seem to be listed there but I mean the Needs No One, Forever Fresh, Never Weary and Forever Full. I may use the traits which lessen those needs like Hardly Hungry or Antiseptic but the absolute ones I only grant to vampires for they have their own versions in their skill tree. To me it just makes way more sense for an immortal supernatural being to have such traits, especially since with vampires you can add challenge in other ways thanks to their weaknesses. With regular sims however I feel like they become complete bores if all their needs are eliminated.
