When I was young in the 1960's, I decided I wanted to a be doctor so I took the entrance exam to go to Medical School.
One of the questions asked us was to rearrange the letters PNEIS into the name of an important human body part which is most useful when erect.
Those who answered 'spine' are doctors today. The rest of us are sending jokes via email.
Have a wonderful day with lots of smiles and giggles
