Absolutely? Barring air, food, water, warmth, sleep and shelter? Some freedom of movement - I can and have done without everything else, including sex, companionship, human interaction, and recreation, although I need those things, I can live without them.
Aside from all the serious stuff like my son, books, love, affection, and sex
I have an insane addiction to hot-pockets, online games (gotta play at least once a day), any hygiene product, music and *sigh* my biggest and nastiest vise of all - cigs.
