I don't have much regret.
The truth is, I am very happy... happily married, healthy and pursuing big dreams. I have been able to do nearly everything I've dedicated myself to, thus far.
But when I see stories like this Double-Arm Transplant at Johns Hopkins Hospital, I wonder about what might have been.
Back when I was in engineering school, I was very interested in Prostheses and Transplants. The place where the integration of engineering and medicine was happening was Johns Hopkins University in Baltimore, MD.
I did not have the money or the grades to fund this graduate work for myself. So I decided that it was more important for me to get a job.
That job was on the Space Shuttle.... still pretty awesome. But, occasionally I wonder if I had pursued my Johns Hopkins thoughts, how my path might have been different.
Make sure you read about the transplant. It's the first of it's kind and the preliminary results are exceptional.
It's just amazing to me how we (the people) can do amazing things. All we have to do is wonder if it's possible.
