My parents aren't africans (they are Filipino) but I surely got the heat vision from them. Now i am imploring the same technique to my kids and I am the envy of my friends at how easily I get the message out to my kids with just the use of my eyes. I'd like to take it further by saying that the reason I am able to do this is because of the deep and strong relationship I have with my kids. The communication at home is clear which is why eye contact is enough to get the message across. If I had to use it on my kids I find it necessary to follow it up with a conversation afterwards.
