"Health is what psychologist Abraham Maslow called a deficiency need, which means when you've lost it, getting it back is the only thing in the world that matters.
Unfortunately, two corollaries to this theory of human motivation are:
1. Most people won't lift a finger to improve their health until something bad happens (they have to hit "rock bottom" to change), and
2. When you've got your health, you tend to take it for granted.
That's why we need constant reminders to keep our focus on health and keep health right on top of our list of life values." - Tom Venuto, author and bodybuilder
