Ah yes, dont mind a bit of DYI surgery. I was 20 years in sports med and first aid, had the highest civilian qualifications available. Once you understand the human body, its just another form of mechanics. Once upon a time before a big night out, we would stuick a bung in the ole forearm, and connect up a saline drip before bed, no hangover if you do that!
Im not as bad as Ranulph Fiennes who cut of the frost bitten stumps of his fingers with a dremel saw, only because the hack saw wasnt doing a very good job.
