Yes agree Costa saved Mick, it wasnt just his leg btw the flesh was rotten so he (Costa) risked spreading the infection when the legs were sewn which could have resulted in death, worst case. All this was presented to Mick, he went with it and Costa is a hero of mine for what he did. Apparetly there was some spiritual element or bond between them. In his own words, Mick said he wasn't emotional and didn't waste time crying about it, which as an attitude makes people assume he was ruthless but in reality he was simply willing to do whatever it took. Another thing Mick claims if he coulda been w/c in 1992 after the accident he woulda quit. Somehow I doubt that but it sounds like this was the pact he made with himself under terrible circumstances to get or even force himself through. Light at the end of the tunnel, faint as it was. A really fascinating tale not well documented imo.
