I should imagine more people can answer the second question than the first question. I don't think it's a matter of wasting time over rubbish. (Define rubbish!!)
What you may think of as rubbish may be important to others. In fact it is a bit insulting to people to say what they think or answer is rubbish.
A little tolerance goes a long way in this world. I am interested in what everyone has to say, not just the world changing things, but the little things in life.
Big things don't always change the world, but little things do more often. If Napoleon hadn't suffered from an intestinal disorder which flared up at Waterloo, we would probably have lost the battle. A small, but very signifcant factor in the battle, which changed the face of history.
I was even interested in your posting!!
