Because I don't produce insulin, I have to put insulin into my body, which means that I have a pen with a needle on it. I have it with me. You have to stick it in your thigh, or your arm - a lot of different spots you can put it.

As I get older and maybe a little bit wiser, you realize how much stuff affects your body and what it can do. Cutting out carbs and sweets and trying to eat just proteins and fruits and stuff like that, more natural stuff, is what I have found has had the biggest impact on me.
