Three times in my life I have been a guest of an ER or Trauma center. Once was pretty bad (pickup truck versus bicycle rider) and it might have been touch and go were it not for an amazing staff of quick thinking, thoroughly trained people.
A big THANK YOU for what you do.
You guys and EMTs are ROCK STARS!
And don't apologize for your perceived lack of mechanical abilities. Ralph Salzer is an Orthopaedic Surgeon in Beaufort, SC. He is also a classic car collector and he used to say that about himself, too ("Boy, I really envy you guys who know how to work on these cars, blah, blah, blah").
Ralph has a 1950's Studebaker sedan that needed the heater air plenum replaced - The original was made from treated cardboard and disintegrated over time. Couldn't find a new one anywhere. Later on, Ralph shows up at a show with a brand new plenum installed in his car. When asked where he got it he said, "I made it!"
When pressed further, he told us that he made the new plenum out of fiberglass leg cast material, shaped over the old original plenum as best he could. It looked and worked fabulous. He (and you) have the same abilities we car guys have, just re-directed to what you've chosen to do. A car bears many similarities to a human body, if you look for them. Plus, it's sometimes fun to get your hands dirty with something that no one is relying on to keep living.
Good luck, and keep asking questions. (And I was (and still am) a computer guy but spent most of my career trying to herd cats.)
