Does something outlive its usefulness?

We live in an old house—so old, that at one time we actually had a built-in ironing board as a “convenience”. Speaking as someone who hasn’t worn anything but a tshirt since the last time I was required to go to a funeral, it’s rather perplexing how that would be a convenience. I’ve become somewhat fascinated by these leftover things that change and time have left behind. I’m curious as to where our experts see this in organizations.
