ELI5: If EMPs can shut down all electricity, why dont they effect the electrical impulses in our bodies?
gpt
First lets look at what an EMP actually is. It is an "electromagnetic pulse", or an extremely powerful oscillating magnetic field. This causes currents to be formed in conductors through induction, and is more powerful the longer the conductor. The result is powerful surges of electricity in the power grid, and electronics relatively small surges of power can physically damage the extremely delicate semiconductors in the chips. That is why electronics are damaged or destroyed by EMPs.

Inside your body is different. We don't have lengths of wire or other conductors in our body; the "electrical impulses" that occur in our body are extremely short range charge interactions between neighboring cells. These *can* be influenced by electric charges being passed through our body such as with a Taser, but an EMP has no way to cause such charge differentials because there isn't any portion of our body that reacts strongly to magnetic fields.
