I don't remember people having food allergies when I was a kid.  We had peanut butter &amp; jelly at school all the time and no one had a problem with it, nor was it considered life threatening.

I only knew of one kid in my class who had asthma, and my brother had hay fever.  Allergies seem to be more common now.  Is it our environment or it is the cleanliness thing that people have nowadays, using hand sanitizer and disinfectants all the time? Or is it all the chemicals in the environment that are causing the allergies?  I've been wondering about that.
