What's Normal?
Many people think that normal means having one bowel movement every
day, but that's not always true. People are different, and so are
their bowels. Normal for one person might be three bowel movements
a day, and normal for another might be three bowel movements a
week. If your bowel movements fit somewhere in that range, then
you're on a normal schedule.
Jojo's note :
Bowel movement is important, it is also very important to check the
quality of your sai.
Sai that is too hard means you not enough water.
Sai that is too watery means you have diarrhea. Duh !
Sai that is just right is the same consistency as your toothpaste.
heeeee.
