Well, some diseases can't be influenced by variables. I have type 1 diabetes since I was 10 years old and it was caused by sheer luck.
As for the study I was born in November. And I think you could categorize type 1 diabetes as a viral infection. For me it is accurate.
Well, that's not really true. Type 1 diabetes isn't caused by 'sheer luck' – there are a whole bunch of known and suspected genetic and environmental factors. The same applies to other conditions, and I'm not sure 'luck' is much of a contributor either way.
When I got first diagnosed they told me it was due to environmental factors, but they didn't know for sure.
No one in my family had have type 1, so I ruled out the genetic factor. I know that if I had a child, he/she would have a higher risk of being sick.
I am not an expert on the subject, but it seems like bad luck for me. I couldn't help not getting the disease.
Type 1 has been around forever. In Ancient Egypt they defined it as the body eating itself.
When I got sick, no one including the doctor suspected that a child could have diabetes. they had me tested for a lot of things, suspected that I had tuberculosis.
These are my experiences anyway.
