If the sequels are anything to go on, yeah, he will, sort of. But it wouldn't be obvious unless he lost his powers and became Scott again, and that doesn't happen very often. I thought this over, and chances are, Scott's human persona would probably age to an old man that looks similar to Santa, and stay that way until he could no longer do his duties (like an accident). But we'll never know because the outward Santa appearance hides that.l.
