Mhh...nah, mainly because I like my character as he is, because I don't consider the time lapse to be that big to simulate aging (at least in my playthought), and because the "raw" form of doing it is pretty buggy AFAIK, and can lead to various bugs.
If I were you, I'd use a safer way, either a patch for it, or the face changer in Dawnguard.
I get the time lapse thing, but I role play that the game takes place over many years, other wise, imagine defeating alduin, ending the civil war, becoming leader of one of the guilds and solving the vampire problem all within a month in game. That would be an impossibly efficient month for a hero haha.
Oh, and I too totally don't know how you would show age for the beast races either. Haha
