Superbugs

I had the chance to read over an article today about how humans are actually "helping" bacteria to evolve and essentially become stronger and more resistant. This is something that we have been told for years was happening, but how many of us actually listen to what is being said. Our school provides industrial-sized bottles of hand sanitizer to each teacher to have in the classroom. I understand the need to have anti-bacterial materials in the building. However, I placed this giant bottle on my desk for student use. Despite the large number of students that I have throughout the day, I was still amazed at how quickly this bottle disappeared. I'm wondering if this is a commonality at other schools, or just the students in my building being so paranoid. I try to explain to them that they don't need to "sanitize" every 10 minutes, but I think my words are falling on deaf ears.

I'm just curious at to what others are experiencing in the classrooms.
