Anyone else having a problem with these dang white hairs?

[JoeBass]

Maybe it's a problem with going gray, but after a couple of passes with a nice, sharp razor, there are always a few of those tiny white hairs that seem to resist all attempts at removal. The normally pigmented hair comes right off, I'm guessing because it's healthier, thicker, and offers more resistance to the blade, which allows easier removal, while that thin, colorless hair seems to delight in just sliding under the blade. Oh, I eventually find the correct direction of attack to get 'em, but it always takes extra, and sometimes extreme effort. Anyone else experience this?
