Morniní Dave, Chris ...
Despite being "empty vessels" and/or "clueless prats", some of us are not too proud to fix kit (whether simple or grand), and have been able to resist any temptation of falling into the trap of trying to become a "pretend medic".
I donít recall ever being challenged by any surgeon (and I dare say Neil has had similar experiences). If you are competent, it generally becomes apparent.
Speaking for myself I never went to university. But despite that, I still manage to do OK when it comes to grammar, and spelling.
Meanwhile, I hope you have a good day chatting with (impressing) the surgeons.
OK, thatís all ... the kit awaits.
