I can see your point, and for the record Im in Cyprus, but (and in part I take responsibility for wrongly estimating what an everyday kit would be for - someone else mentioned a first aid kit isn't really for the general day to day boo boos) I'm genuinely not looking for any actual survival or life threatening type stuff, which it seems a lot of the answers in here tend towards. For example, I genuinely can't imagine any situation I would find myself in where I would need to use a tourniquet. If I do find myself faced with someone that hurt I would already be on the phone with emergency services getting an ambulance there asap (still haven't even heard of anyone who has needed that kind of care here). I am mainly interested in the stuff that just makes certain normal situations where someone else or myself is hurt in a minor way, a bit easier and less miserable to deal with. I guess I got influenced by my category 3 "hiking" too much and used the words "first aid kit", which mislead people as to what I am actually looking for. A better way to ask the question might have been "What medical/health items do you carry around with you every day to make your life slightly easier?"
An example (which again I would put in the hiking category, or the "road" (car) category at least, is a pair of decent tweezers. Sure it won't really help if someone snaps a bone in half, but realistically how often does that happen, and how often does it happen where I am located that someone hasn't already called for an ambulance. It sure is welcome however if you get a splinter and don't feel like asking around if anyone has clean tweezers xD
Edit: I do want to do the first aid course, not just for work but also because I think its an invaluable skill to have, but its too expensive for me to do privately, it just makes sense to do it through my employer, but you know how this stuff goes. They've got a thousand other things to deal with rather than organise that stuff, so while they seem super positive about the whole thing its just always at the back of the mind of the guy who needs to arrange it.
