Heck, I am still trying to figure out how my 21 yr old nephew can build an entire computer, but cannot change a tire or work a walkman. How is that possible. My son and daughter who are 3, know how to use screw drivers and saws....Maybe it was a lack of encouragement from his father or that he did everything for him. I refuse to do it for my kids, unless they try and fail. Then i will show them, but not do it for them
