Most people are making valid points about not lasting long enough in game time to noticeably age and that's because I forgot to mention that I don't go by in game time, instead I pretend more time has passed then it actually has. Personally it's unrealistic to arrive in Skyrim with no skills or weapons then within a week or so end up slaying the world eater, mastering the thu'um, become the head of Guilds, etc. If I went by game time then that means my guy has done all that plus built a home, married and settled down within a couple of months so I pretend more time has passed to make it feel more natural...hence why I aged him a bit.
Oh, I have some characters that are old grizzled vetrans from the get go. I even have an Arthritic Near Sighted Character with Parkinsons who is going deaf. I just keep my legs and arms crippled, and never zoom in on anything. I used to use a HUD mod that made everything blurry, but I can just rub my fingers on my RW eyeglasses to smudge them if I want that view.
Problem with that build is putting the SPECIAL points somewhere that I take out of Perception, Agility, Endurance and Strength into the 3 that are left. It's much harder to achieve this in Skyrim.

Interesting builds you got there. My guys are almost always grizzled from the get go but you've given me an idea to start out a guy with a fair face and then dirty and scar it up over time....perhaps I will start my first Imperial soldier this way and beat him up after he joins the war
If by age, we're talking younger, not older. I always make my characters as young-looking as possible. It just seems weird to put wrinkles on gray hair on a character, and then start scaling mountains.
If I do create a character like that, I'll be parking my butt on the benches in Whiterun's center and demand a Dragonborn fetch me an old warrior's helmet.
This guy would like a word with you: http://www.blackmediascoop.com/wp-content/uploads/2013/02/Screen-shot-2013-02-21-at-3.01.39-PM.png
Don't sleep on old people, I bet he's in better shape then you and he's probably at least 3 times your age
I generally heavily role-play my characters and they retire usually within one or two game years. That's all the time I need to see about everything and do a couple factions and maybe the MQ. I have never considered physically aging the PC for this reason.
Take for example my main guy, Eric. Did the Companions and MQ. Retired. Came out of retirement to fight vamps. Retired. Came out of retirement to build a retirement home. Got married, adopted some kids and retired again. Came out of retirement to fight some old Dragonborn. Retired yet again. If I was going to age him, now would be the time I guess. But technically all this still happened within just a couple years in game.
haha that's not really retiring if you don't stop saving the day
Will he ever truly retire and fade into fables or will he always keep his sword ready? I'm guessing if you're one of those who lose interest behind no more DLC then he's finally retired from retirement
