My father was fairly tall, and had a slouch from always ducking (we lived in Africa, and he towered over most people, and was always banging his head).

My mother was always nagging me to "sit up straight."

These days, I have fairly good posture. Part of it, is because I take a 5K brisk walk, every morning, and that helps me to stay straight. Also, I am not that tall, so I don't need to keep ducking.

I also use a standing desk, and like to stand straight for it.

Tall man living in Japan. I know how that feels. It sorta gets ingrained to always do it to some extend because if you mess up once you bang your head on the doorpost.

Of course my own house doesn’t have that issue (you’d think), but the one toilet on the second floor… so even at home you can’t relax the vigilance.

I do feel that I should set the record straight.

When we lived in West Africa, he was unusually tall.

In East Africa, though, he had competition from the Masai and Watusi folks, who tended to be basketball-player tall.
