How an injury can affect your job? :)

So...To make a long story short I had to get a spot on my arm cut open last night at the hospital. As I was laying there waiting for the woman to come in with the tools and start carving into my arm I had time to think. What if I would've waited even longer to get this done? What if it got so bad that they had to amputate? How would I work as a graphic designer, after going to school for this long, with only one arm to use while manoeuvring around the computer. I stopped to think about the project I did last class on accessibility and realised how truly lucky I am. I give them props for being able to (despite their disabilities) still find a way of using computers, and getting around other difficult challenges in life that they have to face. I sat and thought about how much I would have to adjust if I did have to lose one arm one day. I just wanted to get this out there that sometimes those of us without disabilities take A LOT for granted.
