Here's a breakdown of why:
* Horses are prone to injury: Even healthy horses can become lame due to a variety of reasons like stepping on a sharp object, twisting a leg, or developing an illness.
* Unexpected events: The proverb emphasizes that even when things seem fine, circumstances can change rapidly, and something unforeseen could occur.
* Being prepared: It serves as a reminder to be cautious and prepared for potential problems, whether it's having a vet on call, keeping up with routine care, or being aware of your horse's surroundings.
The proverb can be applied to situations beyond horses:
* Business: A deal that seems secure today could fall apart tomorrow.
* Personal life: A seemingly healthy relationship could face challenges.
* General life: Unexpected events can disrupt our plans and routines.
In essence, "Tomorrow your horse may be lame" is a reminder to be mindful of the unpredictable nature of life and to be prepared for any eventuality.
