TIL you produce about three and a half metric tons of feces and 38 000 liters of urine during an average lifetime.

How many miles of feces? Are we talking to the scale of as long as the Panama canal, the length of New York, around the equator, or to the moon (and back)?
The average density of human feces is approximately 1.06 grams per milliliter
https://en.wikipedia.org/wiki/Human_feces
Normal stool (Type 4) typically has a diameter of about 1 to 2 cm http://d2xk4h2me8pjt2.cloudfront.net/webjc/attachments/73/57bbee4-bristol-stool-chart.pdf
Radius = 0.75 cm
Density = 1.06 g/cm³
Mass = 3,500,000 g
Volume = 3,500,000 / 1.06 = ~3,301,887 cm³
Cross-sectional area = π × 0.75² = ~1.767 cm²
Length = 3,301,887 / 1.767 = ~1,868,000 cm = 18,680 m = 18.7 km
So 18.7km or 11.6 miles
Type 4 Bristol scale or are we talking some other stool types
It’s log scale.
That would depend on the tightness of the anus
Are we talking about someone who squeezes out pencils, or a log-dropper?
Irrelevant. We roll them into ISO standard poo diameter after excretion
