There is something, likely many things, in your life that you don't understand the details of, something that an expert in that subject may chastise you for not knowing. Something that you take for granted that it just works, and never stop to think about the logistics. And that's fine. You have your specialty, they have theirs. And when you need help with it, you don't need to be an expert in the subject because you can hire one for a short period of time. I'll be honest, I don't know how my furnace works. It just does. And when it doesn't, I call an expert to fix it. Because that's gas and fire and a whole lot of pipes and there's an air conditioner somewhere in the mix and I think that's a humidifier attached? Doesn't matter, I have more important things to think about and I don't want to break it even more (or worse, blow up my house). I'll let the expert handle it.
