Why do some people survived after hit by lightning?

Answer 1

The injury caused by a lightning strike depends greatly on the amount of current that enters the body. A lightning strike is very high voltage, but it can be distributed over a very large area (as shown by the dendritic branching patterns). Unless one is hit directly by a return stroke, the current can be carried through the liquids of the skin to the ground without causing fatal damage. A lightning strike on a sports field can injure as many as a dozen players, and yet kill no one.

Some people have been hit more than once by lightning, suffering skin burns (especially on the head, back, or heels) and occasionally nerve damage.
