Lots of things I COULD live without, but prefer not to.
Cell phone -- I rarely use it (it was a gift from my folks, when my dh had just gotten a job out of state, and they were worried about me driving my less-than-healthy car and breaking down. Of course, that could have happened while he was there, but... ;-) and I don't even know the number. It is usually off.
I could live without pollution, but don't seem to have that choice!
We've manage for 16 yrs to raise a child without a gaming system. (Of course, we DO play games on the computer....)
I'm surviving without a basement, but would rather have one... (We have pack-rat syndrome.)
Could definitely live without those aches and pains...
