Perhaps his most famous observations were in his study of thin slices of cork, describing the pores, or cells he viewed.

It's a myth that the definition of a normal bowel movement is having 1 movement each day because that is not true for everyone. There is no rule for frequency of bowel movements, but the general range is from 3 times a day to 3 times a week.
Up to 3 a day is considered normal, 5 is a bit much. In the absence of other symptoms start by looking at your diet to see if maybe you can pinpoint a cause there. If you keep having 5 bowel movements a day you may want to consult your doctor. It may be normal for you but the average person has them a lot less frequently. One or two and day sometimes one every other day is common. You may wish to speak with a health care provider about this.
