[split] Vampires and Vampirism

['thul]

True. constant age = regular movement required. But many incarnations of the vampire mythos do not have such conveniences as choice about age. a far more convenient form would be cyclical age. aging normally, then regressing to say, late childhood around age 80 or so. This however, is not common. Most versions of born (near-)immortals age to full maturity, then stop.
in the cases of those who are only nearly immortal, the aging process might start a few years before death, or even shorter time before, giving them countless years in their "prime".

for turned immortals (classic vampire bite system), the typical age would be whatever age they were at being turned. like the eternal child vampires.
