I don't know, i don't care, and it doesn't make any difference.
If everyone is moving forward together, then success takes care of itself.
Take care of the luxuries and the necessities will take care of themselves.

But why should you care what people will say? All you have to do is please yourself.
Be careful about reading health books. You may die of a misprint.
