Nothing!

My opening thought is about "nothing".

Have you ever wondered what thinking about "nothing" is like. Well it must be very exhausting because it makes the biggest strongest men tired.

Here is the reasoning or so I am told. Men often sit quietly on their favorite chairs or spots in the garden, gazing into the realms of the wise and unknown. The lady in their life will then walk into their space and inquisitively or lovingly ask that most intrusive question, "What are you thinking about, Sweetheart".

The answer, "NOTHING, dear!" and a cheesy smile will usually creep across the mans face.

So you see, men big and small do unknowingly and unwittingly partake in the awesome form of meditation called "Nothingness meditation"...... or maybe they are all just to embarrassed to tell what they were thinking about.
