[mdip]

Not so much overlooked as omitted ... I had originally written "average American adults" but I didn't want to distract into the territory of "how bad our diets are in this country".

My Dad almost always flew alone. So much so that when the plane was packed and we were making an approach into the Sandusky, OH airport, we had a sudden "dip" on the way down that everyone noticed (we were headed to Cedar Pointe, so it was preparation, I guess). My Dad explained that he wasn't used to landing with so much weight and hadn't adjusted the trim correctly[0].

[0] If it wasn't abundantly clear, all of my flying experience ended at about age 17, which was a while ago, and I was never a pilot, so to the extent that I get any of this wrong -- that's why :)
