I have been learning to drive. horses and carriages actually not cars.

It was recommended to us by an expert that we rub the shoulders and neck of a horse with alum daily in order to help toughen his skin up so the collar harness wouldn't make him so sore. I thought it interesting, that we do the same thing for our shaves LOL.

An alternative he said we could use was Malt vinegar. Hmmm...... vinegar as an aftershave treatment. I wonder what my dermatologist would think.
