Back when micro-usb was a thing, I accumulated an ungodly number of cables, way more than can be explained by obvious logic such as 'one per device'. At the time it was great because I never seemed to be more than ten feet from the cable I needed. Then came usb-c so I had to start all over, but I kept hold of all the old cables because of some weird hoarding instinct. A few weeks ago, I had to downgrade back from usb-c to micro and I am hugely relieved I kept all those old cables!

Moral of the story: never throw out old cables ... (maybe)
