Great article but inasmuch as I will love to agree with you, I would love to ask, why haven't our phone chargers electrocuted us since most of them are labeled 2ampere? As you stated above, the let go current is just 0.16amps

Most phone chargers are rated 5V, so this voltage is too low to break the skin's resistance to pass this 2A to the body. Remember current is both a function of voltage and resistance. Another thing is your phone chargers are insulated; it's not as if while charging your phone that the 2A is flowing through your body.
Disclaimer: it could be fatal in very rare circumstances where there's water to make the skin more conductive as it lowers your body's skin natural resistance.
