What I know is when I was a kid, it was standard to keep them on.
I can't think of anyone I know my age or younger who would keep their shoes at home.

My grandfather in France had a clock that was receiving a radio signal I think from Strasbourg.
They've been around for a while.

I would use it to adjust my watch.
Nowadays I use raw GPS and any mobile phone is synced from the network anyway.
I thought it was just a joke about the tai chi looking pose = old people in parks. Did I understand wrong?
