Excuse me, but I just have to say this. You are more stupid than a paramecium. - Bill Bryson

An increase of only a degree or so in body temperature has been shown to slow the replication rate of viruses by a factor of two hundred — an astonishing increase in self-defense from only a very modest rise in warmth.

Take a moment from time to time to remember that you are alive. I know this sounds a trifle obvious, but it is amazing how little time we take to remark upon this singular and gratifying fact. By most astounding stroke of luck and infinitesimal portion of all the matter in the universe came together to create you and for the tiniest moment in the great span of eternity you have the incomparable privilege to exist.

For endless eons there was no you. Before you know it, you will cease to be again. And in between you have this wonderful opportunity to see and feel and think and do. Whatever else you do with your life, nothing will remotely compare with the incredible accomplishment of having managed to get yourself born. Congratulations. Well done. You really are special.

The upshot of all this is that we live in a universe whose age we can't quite compute, surrounded by stars whose distances we don't altogether know, filled with matter we can't identify, operating in conformance with physical laws whose properties we don’t truly understand.
