Two thoughts

I m back from the Christmas break and back in the office.

Two little thoughts to get you thinking (and commenting):

The word invalid, used to describe people who through sickness or
disability may not be able to walk or suffer weakness or such things.
Look at that word.

IN - VALID.

I am not usually one for political correctness, but on reflection
that is one word I am glad to see falling out of common usage.

Is alcoholism, binge drinking and smoking a form of self-harm?

Answers on a postcard please.
