If you can ear me, here's a tip:

If you're like me, you probably find that you often fail to plan or fail to act.  Sometimes both in equal measure.  That means you might overlook doing something that would certainly be in your best interest, like performing any level of cleaning to the underside of a vehicle before beginning extensive work underneath it.

The next time you're under the car banging on shit and causing several decades of road grit to fall directly into your ear, remember the used nitriles that litter your work area like the autumn leaves once blanketed (or maybe still do) your project car.  At least one finger of one of these little guys is clean after having been turned inside-out, which makes it a perfect impromptu ear plug once it's been freed from the rest of the glove.  As for the eyes, I dunno. . . Blink faster or something.
