I have always thought that there was something a bit vain about worrying about gray hair--but it is becoming increasingly apparent that being "old" (you know, more than 40) is a major problem for software engineers looking for a job. For the next time that I start worrying about this, any suggestions on products that work well, especially on a beard? I cannot imagine using such a product on a regular basis, but once through the interview process, I know that my performance is quite sufficient to overcome the prejudices against being ancient, and I can then go back to being myself.
I somewhat resent having to play games like this, but it could be worse, I suppose. There was a time, only a few decades ago, when some Americans had to use skin lighteners for the same reason.
