I believe we are increasing in the number of autoimmue disorders.

Alergies is a clear sign that these are not 'hidden', 'waiting to be discovered' symptoms.

My personal view is that this a combination of the following top factors (in that order):

1) long-distance travel causing quick spreading of various infections illnesses stressing our immune system

2) Food (too much sugar and carbs)

3) Water and air pollution

4) vaccines 'boosters' chasing immunity to rapidly changing pathogens
