I've changed my hairstyle as well.
Normally, I wear my hair fairly short, parted on the left
(remember Peter Gunn?). But since I've quit visiting my barber and its getting quite long, I've taken to brushing it straight back. The result is something like a white-haired, Fu Manchu mustachioed Christopher Walken. Or as my wife describes it, an aging Moe of the Three Stooges.
Hopefully, it will eventually get long enough for a pony tail. But I swear, I'm not going for a man-bun.
