How often do you cross a bridge?

[Syt]

Twice a day - the bridge in the middle across the Danube. The subway line is below the street.





I also cross the Danube Canal, but the subway line goes underneath it.

The new bridge is a replacement for the old Reichsbrücke which collapsed in the 70s.

[Brazen]

A couple of times a month. It does the soul good to cross the Thames and see the horizon even from the middle of the city.

On my way to work there's a river and a canal that I pass so 4 times a day.

Somebody's been reading a biography of Immanuel Kant. 

Who?

Seriously?

I know who Kant is, I'm wondering who Viking thinks is reading his biography.

The OP obviously. Kant is without a doubt the most notorious daily bridge crosser in world history.

Oh, I didn't know that about him. Nor am I reading his biography.

I'm reading Malthus's recommendation : The Time Traveler's Guide to Medieval England: A Handbook for Visitors to the Fourteenth Century

[Viking]

Oh, I didn't know that about him. Nor am I reading his biography.

He famously took regular daily walk so regular people literally set their watches by it (starting the trope). His rout crossed all 7 bridges in Königsberg at the time. This regular habit actually resulted in Euler famously mathematically proving that Kant could not take his walk crossing each bridge only once ending where he started. Kant actual path is lost to history.
