178cm is pretty average is it not? Though the seats need to accommodate women as well. So your average is closer to 170. Still, the seat is comfortable for my back, the had rest just push my head forward uncomfortably far resulting in neck soreness even with good posture. Maybe i have a long head? Idk, guess im a xenomorph.
Turning it around is and feels dangerous, but extremely comfortable. Wish i could tilt the head rest just a bit. Maybe I'll just permanently bend it. Feels like if i got rear ended there would be a lot of pressure on the base of my neck.
Both were massive empires. Makes sense that imperialism would put selective pressure on language. Historically you're either limited in words by space on a paper or what can be easily repeated by messengers.
