While watching this video I honestly had tears in my eyes.
I know what re-evaluating all these "normal" things (we usually give for granted) means, after going through such a hard experience.
Every single day is a preciously increasing small step toward the new life...wow...I'm so happy for you!!
I just read about your 2009 double lung transplant (sorry..."it's better later that never", they say in my country).
I hope that your recuperation was speedy and painless, and that now those long (and amazingly "educative") Orbiter videos are now so much easy for you to make.
Best wishes from a friend (and your videos' fan) of Spain. Go ahead!
