The world is a big door knob that transmits germs. People touching and touching..... and sneezing and touching; its no surprise that people get sick, especially students. I've counted, and I touch a door handle 80 times a day (for every door you enter, you also exit). This means there are 80 opportunities for ME... as 1 lonely student to transmit germs to 20 different locations across campus. That's just for one day and one student. Multiply that by 10,000 students/staff at the Poly campus and that would be 800,000 opportunities to transmit a virus or flu or nasty bacteria to others throughout the campus in 1 DAY !!! There are toilet seats and counter tops consisting of material that kills germs. My solution is to make door handles out of the same bacteria fighting material. This will save schools... nurseries... day cares and hospitals from having to fight the battle against the "dirty door knob" as well as save thousands on medicines.
