Everything came easy to me in life. I could always shake off difficulties, like water on a duck's wings. - Rita Levi-Montalcini

Better to add life to your days than days to your life.

I consider imperfection a Darwinian spring of natural selection. For example, present day insects are identical to those of six million years ago: they were already perfect, and there was no reason for them to change. Man was instead imperfect, and this was the proxy for his own development and evolution.

I'm an atheist: I don't know what it means to believe in God.
