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.
Normal bowel movements are highly variable between individuals in terms of frequency and in terms of form (see the figure below). People have normal frequency of from three times a day (usually after each meal) to one every other day. Thus is it is normal for humans to have highly variable habits, but each one of us tends to have a regular habit of bowel evacuation - most commonly, one per day and usually at about the same time of day.
