The next time you hear some yuckster say bad things about NASA be sure to point out a few facts. Without NASA we'd sleep a little less comfortably, see a little poorer, and be a little poorer. You see, without Space exploration we'd never have invented memory foam, which we all seam to have, in some form, on our beds. Scratch resistant lenses would never have been invented. Plus we'd be replacing our tires a lot sooner because NASA is the reason we have long life tires. Now, if this yuckster drives you to fisticuffs, well, just stand over him and tell him his teeth can be fixed with Invisible Braces...Thanks to NASA. But really, before you regress to violence, try to convince them over a nice, good tasting, glass of water, which came from your water filter pitcher. Thanks NASA.
