Just out of curiosity, what sort of waist circumference would this work out to? Plainly more than 16 inches and less than 25 ≈ 8π (or 8τ/2), so maybe about 20 around? I don’t really know the eccentricity of a typical waist, and wonder just how unhealthy it might be.
Wait, does it count as astroturf if you’re promoting a book that you haven’t written yet?
