Re: A long time ago
As MacGyver proved, you can recover from almost any disaster with duct tape. I say "almost" as some fixes work better if you also have some cable ties...
OK, a hot-melt glue gun is also useful (especially my battery powered Bosch one, that charges over a micro USB). I used to add Araldite to the list, but hot-melt has replaced that for most repairs. Even cyanoacrylate glue goes to the back of the cupboard.
And a Leatherman (replacing my previous Swiss Army knife) - Gibbs' rule 9.
After all, what have the Romans ever done for us?
