It is far easier and safer to prevent illness by the observance of the laws of health than to set about curing the illness which has been brought on by our own ignorance and carelessness. Hence it is the duty of all thoughtful men to understand aright the laws of health.

About this quote

Prevention is cheap and quiet; cure is expensive and loud. Learning the ordinary rules that keep a body well and following them costs a little attention now, while ignoring them until something breaks hands you a far harder problem later. You trade a small, boring investment against a large, painful bill.

When to use it

  • Flossing nightly spares someone the drill, the pain, and the bill of a root canal years on.
  • A driver who services the car on schedule avoids being stranded by a blown engine.
  • Saving a little each month builds a cushion so one emergency doesn't turn into a crisis.
