I've lived out of a bag for large portions of my life as well. But I've never slept in a gym. Your story reminded me of an LIE I know. He would often sleep on the couch of his house because it was close to the fire place. He had a heater but he didn't want to set it up because he didn't want to be comfortable in his bedroom in case the fire went out and the house froze. He had been doing this for years and could never understand why he wasn't getting enough sleep. Also, in the summer he did not have air conditioning when clearly his place needed it because of direct sun exposure. He didn't believe that a portable unit that could be rolled around and attached through a window, but is not permanent, would do anything. He had just been living this way forever, sweating like a whore in church every summer..... got him hooked up from one at a department store and set it up and he loves it.
