You must be attentive enough to your impulses to catch yourself wanting to do it before you actually do it.

It takes years to develop that level of attentiveness, but it's oh-so-worth-it. And not just because it lets you avoid the seasonal colds :)

Interesting. I have an absolute control over this kind of things. If I decide not to touch my face with my hands it just happens. It feels like mentally setting an exception in my loop. As soon as the hand comes closer to the face or my eyes itch, I realize what‘s happening and stop. I never saw that as anything special, though, is it?
