If this keyboard drains my electricity, wouldn't I feel totally drained after an hour or two working on this keyboard?

Even physical resistors change over time. They are sold with tolerances.
I would imagine a person's resistance would change over time as well.
Get a cut on your arm, resistance of your arm changes.
Try a new moisturizer, the resistance of your hand changes.
If your body is cold and outputs a millivolt less than the current will change

It would be amazing if they found a way to do it but ohm's law applies for everything in nature. You don't have your own personal "Current Rating".
If the resistance changes then current changes as well.
