User: Is it possible to live life without having to use a door?
Assistant: While it is unknown if this question has ever been asked.  It is definitely possible to live your life without using a door.  This brings health benefits caused by not needing to touch doorknobs to living/working in areas with more access to air flow.  Many commercial spaces now feature automatic sliding doors and open floor plans to maximize the health benefits of not using doorknobs.  

This question primarily seems to be relevant in the context of suburban/urban dwellers where most doors are constructed and utilized.  While some may argue that privacy screens, hanging beads, and flaps could be seen as doors they are not being considered in this case.  Regions that have a low prevalence of doors might not realize this as an issue at all.

So yes it is possible to live your entire life without having to use a door but the difficulty increases exponentially the closer you get to an urban area.
