Health is the soul that animates all the enjoyments of life, which fade and are tasteless without it.

When in doubt, don't.

Any society that could come here could pick up the lights from New York. What should we do about that? Should we darken New York from now until the last human expires? Would we want to turn off all the radars at JFK airport?

Necessity is the mother of taking chances.

The only way to keep your health is to eat what you don't want, drink what you don't like, and do what you'd rather not.
