I was talking the other day and remembered that Rudy told me how he got the money to pay for his first recording machine. Even though he had been an engineering student, he didn't have the expertise to craft the technology himself as it requires quite specific skills. He commissioned someone he knew to make one to order and raised the funds - by repeatedly donating blood to a blood bank that paid a small sum each time.
At least I think that is what he said.
If so, then that's what I call devotion.
