if static electricity produces high voltages why isn't it harmful to people? how is it different from transformers and other sources which also produce high voltage but are harmful?

Static electricity is harmful when enough current is involved, e.g., a bolt of lightning.

Tim Mooney

The current in static electricity is extremely low, on the order of a pico amp (1/1000000000000). Involuntary muscle contractions (can't let go!) occurs at about 10 milliamps (10/1000). Clearly, the current in a typical static discharge is far below this level. In a transformer, ther is the possibility of 1000 amps or more. This may very well be lethal.
