If we can possibly avoid wrecking this little planet of ours, we will, But-there must be risks! There must be. In experimental work there always are!

Hee that looseth his due, gets not thankes.
Emptie vessels sound most.
He that believes all misseth; he that believes nothing, hits not.
In the mouth of a bad dog fals often a good bone.
