I agree with Karen; I think you would age normally. Once you leave your timeline, you stop existing in that timeline. So if you spend a year somewhere else, you are a year older when you return because ... well, it's the same you who is returning. (Gee, I see how this can induce carpool mirgranes ...
)
And, of course, you could still be killed in another time. If you traveled to the future and were shot there, for example, you could never return back to your original 22 year old life anyway.
Ah, gotta love those time line conundrums. <g>
