Useful information - Joe Smith's TED Talk

I have always used 2 paper towels, but after watching Joe Smith's technique I will definitely try to reduce that number. It is really simple to do, and the only annoying part is shaking your hands, but if I make it habit I will do it naturally, without getting angry.

I thought that for kids one towel is enough, and I remined them all the time not to grab two, but now I know one towel is enough for me, too.
