OK, I admit, I'm curious! What have you needed it for that is first aid related?
Cuts, small ones and deep ones. I always take some with me while fishing in Canada (remote). Slip with a fillet knife or tear up a finger or two while trying to release 40+" pike while he's still in the water (they'll make a terrible mess of your boat). I'd give up band aids for super glue anytime.
Not only that but have you ever tried to sew yourself back together?
Squirt some glue in a cut and push the skin back together and your done.
Don't get me wrong it stings like hell but the pain will subside.
