On my first job for CBI many years ago we dropped two guys in six months from over 50 ft. Both lived. One was my wife's brother. He lives here close to us in AZ now. About 60 yrs old, BUT, on his 4th hip replacement, he has degenerative arthritis, bad knees, bad shoulder, and is pretty much a mess. And would you believe, he still does odd jobs but just a couple of months ago got put on full disability.
He has been retrained twice but the doctors finally said he just can't do it.
Have a Great Day, Brent
