OK,
There is a lot of misinformation taking place here. 3-4 mA (that is milliamp) applied across the heart muscle will cause the heart to stop beating. (It actually adapts, thinking that the brain has stopped sending little pulses and has now switched to the bigger pulses. The heart is a muscle controlled by electrical impulses from the brain.) This 3-4 mA is critical and the reason that ground fault interrupters are tested and must react at 3-4 mA.
Most reports of electrical shock do not result in death simply because the circuit through the body that causes the shock does not cause current to flow through the heart.
As to static electricity, the voltage and current at the point of entry are dissipated by the body's tissues and a great deal flows on the surface. The shock causes localized pain, a muscle contraction and in rare cases a small pin point burn at the point of entry. In the ultimate static electricity strike, i.e. lightning, the bolt carries current in the millions of amps. Should you receive a direct hit, which is rare, the heat generated by the current flow cause significant tissue damage which usually results in death.
Now to the static problems with electronics, The spikes are not only causing false triggers, but the ringing associated with large voltage spikes also causes spurious data to be entered into digital circuits. In some cases the the protection devices that are engineered into the circuit cannot react quickly enough to limit the voltage and the resultant spike punches through the internal materials causing permanent damage to the device.
