You know those commercials for the Off clip-on thingie for repelling insects? They came out last year or so, at least up here. But I don't know anybody who has actually used one. So I don't know if they work or whether they're so powerful or aromatic that they're worse than just slathering yourself in Cutters or DEET or whatever.
The commercials make it look like those belt mounted personal shield generators they use in Dune. You know, project a hemisphere of shield protection. My problem with this? What if the mosquitoes are armed with knives and move in very slowly, so they can penetrate the shield? What good are those shields gonna do now?
See, this is why you need to be up on your genre literature. Because if you don't understand these SF/F references, why then you might make some terrible consumer choices. Unleash forces you don't want unleashed.
I'm just sayin'.
