There's no health benefits to fasting: still. Your body responds in some paleo-way; calcium leaks from bones to balance lost ones escaping during the ***. Always this homeostasis while peeing. A setpoint.
There are those who fast because that is what's left to them, a prisoner in cell, on the street, sitting in cubicles feeling rightness with the same wrong skin as e's fellow mate.
E does the daily pet cheats too, until e's tired of it all, until e wishes that there WAS a great fallen Leader to blame, or a giant green Tank to stand against rice's grain while holding defiant plastic shopping bags.
When even violence has been taken away: still. We believe in peaceful God and fast, fast or set ourselves on fire because the concrete doesn't burn.
