"I'm too intelligent to have children"

"I'm too intelligent to have a child".

I am positive that at some point in my 30 years of wandering often aimlessly around this rock, I would have said this. I was an outspoken child who was quite impetuous when it came to dealing out my strong opinions. Some people might argue that nothing has changed, but I would like to think I have been around long enough to have learnt some tact and diplomacy.
