Daniel Suelo is 51 years old and broke. Happily broke. Consciously, deliberately, blessedly broke. Not only does he not have debt, a mortgage or rent, but he does not earn a salary. Nor does he buy food or clothes, or own any product with a lower case 'i' before it. Home is a cave on public land outside Moab, Utah. He scavenges for food from the garbage or off the land (fried grasshoppers, anyone?). He has been known to carve up and boil fresh road kill. He bathes, sans soap, in the creek.
