I have met a few people with allergies, I will make a video.
Naples for pizza.
Of course there are real allergies, and people need to take care. However, I agree 100 percent, that 70-90 percent of people are volunteering to have allergies.
From my experience, only 1 in 100 people are even self-aware enough to know which foods cause them trips to the toilet. Plus being that 50-70 percent of Americans over 40 are incapable of controlling the temptation to eat.
In the end, the average human on the planet is finding problems to volunteer to have.
