Do lười mà thôi

con lười khi đi ị cũng đau như đau đẻ :D

Sloths (con lười) have one of the most unique (độc đáo) rituals (nghi lễ) when it comes to defecation (đại tiện). Unlike most other animals, the sloths only urinate and release their bowels once a week.

When a sloth does their weekly poo, a lot comes out. Rebecca Cliffe, a sloth biologist at Swansea University, observed the sloths and could see "their stomachs physically shrink" when releasing poop. The animals can lose up to one-third of their body weight during defecation, and the poop can weigh over 2 pounds.

The sloth has to physically climb down from a forest canopy to poop. To start the act of defecation, a sloth initiates a ritual dance that helps with the process. The dancing creates a tiny space in the dirt for the turd (cục phân; người đê tiện, đáng ghét). The sloth can also do a second dance just to get back up the tree.

As the sloth only goes to the bathroom once a week, the turd emerges as a long piece, which scientists say, resembles an old banana. Constipation (táo bón) is a normal part of a sloth's life and consequently, each bowel movement can be as painful as childbirth.

...These animals have a slow metabolism (trao đổi chất; chuyển hóa), and it can take them a month to digest (tiêu hóa) certain types of food.
