Over 80

I read through a little bit of research tonight regarding upcoming potential treatments for autoimmune disease.

The new possible treatment still has a long way to go along the avenue of research before it is put to the test, but it could very well be a game changer for millions of people suffering from autoimmune conditions.

There was one sentence in the article that had me confused. It said that it could help with the over 80 types of autoimmune disorders that millions suffer from. Are there really only about 80? I thought there were way more.

Here are the autoimmune conditions that I suffer from:
Crohn's Disease
Chronic Pouchitis
Hashimoto's Thyroiditis
Psoriasis
Sjögren's Phenomenon
Raynaud's Phenomenon
Macular Degeneration
Ankylosing Spondylitis

So 8 that I can think of right now. That means that I have about 10% of all autoimmune diseases out there.
Seriously?
That is a huge number.
What the hell is wrong with my system?
