Is it possible that allergies have always been around but in todays world we are going to doctor way more than before?
We run to the doc for absolutely everything. Doctors are way more knowledgeable and we are diagnosed with all kinds of things. Maybe things that we had 50-75 years ago but with no diagnosis. We just worked around them.
That kid that could not run in PE class was called a weakling but in reality had severe allergies?
