Myron you're about the last person in the world who'd have to worry about hitting your head on the range hood.
A photo that I'd love to get for this discussion is what I'd see in the 19 lounging on the dinette seat looking along the counter. At night, with the range hood light on, without the fan on, the view of the steam etc. roiling out from the stove heading for the ceiling was very visible. Prompting the comment from me, "turn the fan on".
Like Jim, I've cleaned enough range hood fans or replaced them to know that there's a lot of crud in the air. I'd rather have it up and out, not on my Maxxfan.
People without a range hood shouldn't complain if they have excess condensation and expect any sympathy here.
