All spiral staircases have a single guardrail. That’s why they aren’t double helix staircases.

Look, I know ads are the mechanism for some sites. And I don’t normally “this site gave my phone cancer”.. but on IOS with blockers, everything except the text on the site can go fuck itself.

Been to the top of the Eiffel, it was a long enough set of elevator rides to flirt with and eventually date a French girl. So that probably wouldn’t have happened on stairs.
