Think of some of the things that used to be very popular, but which practically don’t exist anymore. Like vinyl records. Or fax machines. Or… door knobs?

Door knobs may become a thing of the past, with door levers taking their place.

That’s because Vancouver, a large city in British Columbia, recently changed its building code to say that new buildings will be built with levers instead of knobs.

The city’s building code is changing to levers because they are easier to open. People with arthritis, for instance, often find door knobs difficult.

Using levers will make doors as accessible to as many people as possible.
