There is research on how to control microhabits -- things that you do without really thinking about it, you take away the opportunity to do it.

Even if standardized packaging had no effect at all on current smokers and only stopped one in 20 young people from being lured into smoking (in the UK), it would save about 2,000 lives a year.

If you never touched Your Face, Your Face wouldn't matter if you didn't wash your hands. Your hands could be as dirty or as contaminated as you like, the only reason why it's important is because eventually your hands are going to come in contact with a mucus membrane. It's the mucus membranes that are the key...( they) act as the pathway into the body.

The fact that it's mainly droplet-based and that it survives quite a long time on surfaces means that these fomites are going to be a really important route of transmission, we need more hand awareness and actions that are incompatible with touching Your Face.

If you've got a big problem( people think) you need a big solution, face touching [ appears to be ] such a trivial thing. It's almost silly, and it just doesn't feel right that stopping face touching could make much of a difference.
