A Medical Kit

In addition to band aids, a bottle of Betadyenes/p found in every
E/R room on the planet.
snipped other useful stuff
I keep all of the above in a sealed white plastic container with a big
red cross painted on it.

Excellent idea. I made a trip upstairs just a couple days ago to wash
out a minor cut, but a little disinfectant and a bandaid would have
been plenty. One related item I use fairly often is super glue -
actually holds minor cuts together for a couple days, instead of just
covering them up. The "liquid bandaid" they sell isn't even close.
