It's True - The Bristol Stool chart was produced in 1997 by Heaton and Lewis, two Bristol researchers, to help to rank stool types for research and clinical purposes. It's a seven point scale ranging from number 1 - small hard lumps like nuts (rabbit poos) - through number two (appropriate enough), which is a lumpy sausage, and up to number 7 - runnier than water. According to the scale, the most comfortable to pass is a "type 4" stool, described as "like a sausage or snake, smooth and soft".

It's True - Most people have between 100,000 and 150,000 hairs on their heads (before they go bald), which is an average of 150 hairs per square centimetre.

In your programme about allergies, you mentioned that the cause of cat allergy is the saliva in their skin.
