One of the most soul destroying issues with my brain injury is the frequency of losing things. I try to just ignore it and let it pass but of course sometimes you really need your keys. So I bought some Lupo devices which are key fobs that talk Bluetooth to your phone. If you lose stuff which is near you can tell it to make a beep sound so you can find it, and if it's out of range you can at least look on a map for the last known location. It's not perfect, to make the battery life last it is not very responsive and it's quiet when it does beep but I've used it twice to find stuff just in the last weekend and it worked.
Except now I've lost my drysuit. This thing is bulky and bright red. I've no memory of what happened to it but there's very limited options in my movements, but it has vanished. Soul destroyed. If only I could find my glasses I might be able to search better for it.
