I live every day like it's the last day of my life

I live every day like it's the last day of my life.

Every morning I wake up real early, and I spend maybe three hours on the phone making funeral arrangements.

Pasteur's rabies vaccine

In 1885, after 15-year-old Jean Baptiste Jupille was severely bitten while with his bare hands he killed an attacking rabid dog to protect five other young shepherds in Villers-Farley, France. He shortly became the second person treated by Louis Pasteur's experimental vaccine for rabies. He was fortunate to be taken to Pasteur's laboratory. Pasteur's collaborator Emile Roux had thought of attenuating the power of the infection by exposing strips of fresh spinal marrow taken from a rabbit that had died of rabies to dry, sterile air for various lengths of time. The vaccine was a small piece of marrow ground up and suspended in sterilized broth. It had first been used on Joseph Meister on 6 Jul 1885. By 12 Apr 1886, 726 people had been treated.
