Probably right on college kid thing.
If you're saying they are engineering and computer science majors, just imagine how many keyboards and mice they touch on a daily basis...nobody sanitizes keyboards and mice before using, and colleges tend to have what I like to call "public computers" (computer labs open to all students, coming in from everywhere, sneezing on their hands then using the hands to type and operate the mouse...then comes the next kid, then the next kid, then the next kid.) Then they come home, having built an immunity from so many random disease-infested keyboards, and they sneeze the new strands all over the gym equiptment. You are more affected by this as you have not been building up a tolerance all semester.
Stumbled into Primal due to food allergies, and subsequent elimination of non-primal foods.
