Is it normal that I can't think of any object I couldn't live without?

I think I'd go through serious withdrawal without music, and I need objects to listen to that. I'd get bored to the bone without anything to do, and objects are important for doing basically anything. People have been carving objects for as long as we know there have been people and not all of those objects have been basic necessities, so perhaps objects *are* a basic necessity in that we need them to satiate our crippling boredom and prevent ourselves from going mad. By that logic, perhaps there's no single object (aside from headphones, an MP3 player and a charger) that I couldn't live without, but at the same time losing all my objects at once would be too difficult for me.

That's not to say I don't think a lot of people would be surprised by what they could do without, because I think they would. So I think you're normal.
