Health is your most valuable possession, and it's priceless.
Poor folks can be rich in health, and millionaires can be paupers.
If you are in your forties, then you can lock in the richness of health right now. For example, we hear that with each passing year, our cells reproduce more slowly. This means that the healing process takes longer. I'm not concerned if it'll take four days or four weeks longer than when I was twenty. The important thing is that I will heal.
