These pictures represent some of the things a person with diabetes needs to live a healthy life. Granted, we have an obscene amount in our house with 4 of them but this is diabetes.
The big guy in this picture loves sports. He walks regularly, he tries to eat healthy despite a crazy busy schedule of teaching and coaching. He hates taking medication of any kind, yet he has to every single day. These medications that work to keep his foreign kidney functioning, take a toll on the rest of him. His pancreas can't keep up. He didn't ask for it, he didn't choose it but he has Type 2. Now, in addition to his daily dose of pills, he checks his blood sugar and he takes insulin shots. This is diabetes.
Here are a couple of links that summarize the differences and the causes much better than I can: http://goo.gl/On5Szp, http://jdrf.org/life-with-t1d/frequently-asked-questions/ CrossFit, you got it very wrong. Diabetes of any type is hard work. People living healthy lives despite it deserve your respect--not shame.
