#63: Open your doors (or replace them etc.)

Doors are a major barrier for lots of people with limited mobility or dexterity. Do you have any doors that are habitually kept closed that could really be left open? What about heavy doors that could be replaced with lighter, easier to push newer models? What are the handles like? Round doorknobs are much harder to manipulate than lever-style knobs. Try to visit all the doors on your public floor and note for each one if changes could be made that would make them easier to deal with.
