who lives it.
I was diagnosed with type 1 in my early twenties and assumed an active life had just got a lot harder. Since then I've learned to snowboard, kept training and got ridiculously mediocre at golf. I wanted to build a tool for Type 1s who refused to let the condition decide how big their life is.
