Dear journal,

My journey is almost coming to an end as I reach the rectum, the last 20 cm of the large intestine. Anaerobic bacteria in the colon takes up space and nutrients and, in that way, limit the ability of pathogenic bacteria in the colon from proliferating (if there's no food, the raw materials needed for them to multiply aren't there and if there is no space for them to grow, they simply can't grow and expand their numbers). Here, what is left of me is compacted into feces.
