Oddly enough, I'm thinking this is cool. The stark white contrast against the darkish rest is kinda of nice, and I'm thinking the process should be interesting to watch. It *should* make me feel old, I guess, but it doesn't. Age is an acheivement, after all.
Also, of course, it's not like anyone will see it. My hair spends a lot of time pinned up and hidden under hats - I'm only noticing it now because I just washed it and I'm giving it a chance to airdry before Shabbat, as opposed to, well, pinning it up and hiding it while it's still wet so that I don't miss my bus for work.
