There is a fact that says that if you stay in the toilet for too
long spending your time shtting and reading... there is a high
chance of you developing piles (haemorrhoids) as you are allowing
your stool to compress towards the mucosal lining of the anus for a
longer period of time...
The concentration power needed to poop is diverted to the brain as
you read your text, hence you "forget" to poop, so you leave the
poop there for a longer time, and hence compressing onto it and
loosening the smooth muscles and the elastic tissues which holds
the bands of blood vessels there...
