To some extent that’s probably because people just died of their allergies when they were young and it was probably rarely known just why. But there has probably also been an increase in allergies. I’m no expert, but I have read stuff suggesting that living in a more artificial environment (homes in cities) without exposure to natural allergens is making people more sensitive. My kids grew up in a country home “eating dirt” and have never had problems, FWIW.
I have read a lot of articles that support your theory.
The immune system needs to learn to work right at a young age.
I also remember the days when kids were alleged to have died from choking on a peanut, something you don’t hear of today. I have wondered for some time now if it wasn’t anaphylaxis that closed their windpipe.
As an aside, didn’t this person carry an Epi-Pen and Benadryl? Someone with allergies so severe should ALWAYS be prepared for an emergency.
I’ve always been careful of my immune system. In the 6 years of Navy service, I only took the vax that were required then once I hit the fleet, I was able to skirt vaxes by knowing people n calling in debts owed. My wife recently forced into a vax for her Biologic regimen, but our research showed the vax downside was better than the disease she is fighting to put into remission.
