Word Grrls / Cave Life for a Year

What would you need if you planned to live in a cave for a year? Think about things like a lack of sunlight, heat and the dampness. Also, basic essentials like clean water, sustainable food, something to sleep on, something to wear, and something to do day to day to keep busy. Forget your phone or laptop, the cave doesn't get Internet for more than an hour a day when the signal hits it just right.
