Water

From the book, "Badass" on Amazon

“Not too many years ago few people worried about being hydrated.

Touring motorcycle riders would ride all day long and not have a drop of water.

Then they would wonder why they had near death feelings later in the day.

Mistaking their feelings for a thirst for beer they would swill a few bottles.

Then they would wake up the next day so dehydrated,

their urine looked like the Red River...

and their skin had a distinct sun-dried raisin look."
