"If your average homeless person spent 30 to 40 dollars a month on a gym membership, they could shave and shower..."

"... keep warm for most of the day, maybe stay fit and like they'd have a good opportunity to look at jobs," said a law student, who chose to go homeless to make life more challenging. Turns out it made life better in some ways: "It saves time... You know, all the little ways we waste time in our homes, watching TV or cleaning. I feel like there's a substantial amount of time I'm saving by not having a place."

Consider the possibility that a gym membership is more useful than an apartment, and quite a bargain. If you join a 24-hour gym, you could be safe and warm indoors — getting fit and cleaning and grooming — during the dark hours, and you can get your sleep — as this law student did — in libraries during the day or evening.

It's interesting to think of strategies for living without a home. It's a predicament that is so bad for many people that it might seem a bit insensitive to imagine doing it in a positive way or to experiment with it as a temporary challenge. But let's overcome our reticence — if any — and talk about it. How would you carry out your own personal adventure in homelessness? Picture yourself doing it well. What would you do?
