Because lightning strikes destroy people's own resistance, it reduces people's resistance (people are conductors and people have resistance), and the current is like water flowing downwards, which will be preferentially conducted to the bottom of the resistance.
If two people stand together again in a thunderstorm, then lightning will give priority to this person.
That's why "lightning strikes you once and will strike you again" …
As long as the current exceeds 36V, it will affect people. Especially for ordinary people, it is no problem for some non-ordinary people to touch the switch, because his own resistance is much higher than that of ordinary people, and 220V will not feel anything. 220 volts is enough to electrocute a person.
But sometimes electric shock has no serious consequences except paralysis, that's because you have been a conductor for too short a time. Suppose you stay on the switch for a few seconds, it must be fatal.
Similarly, although lightning is a high voltage, if the high voltage acts on people's bodies for too short a time, it will only destroy people's resistance and will not directly kill them.
