What a Snake Bite Actually Does to Your Body (Hour by Hour)

The strike takes 70 milliseconds — faster than your nervous system can register pain. What happens over the next six hours is one of the most sophisticated chemical attacks in nature: a venom cocktail that digests tissue from the inside, switches off your blood's ability to clot, and — in some snakes — picks the locks on your nervous system itself. This is snakebite, hour by hour: the lymphatic ride, the 20-minute clotting test, the eyelids that fail first, and why the doctor who finally has the antivenom… waits.
