Perhaps not L & C canon, though. Time Minear, the writer of Brutal Youth, is on record as stating that he intended that episode to imply that the longevity scale was more or less balanced as a result of Clark having given up some of his 'life force'.
Just popping in to say that Minear saying that doesn't make it canon for me. Now, if it had been stated
on the show that would be an entirely different matter, but since it wasn't and we got a very vague, wishy-washy "Nobody knows how long they've got" instead , I think Clark's lifespan is open to interpretation.
P.S. I love Lois, warts and all, and don't want to see her punished. To me, she's a more interesting character than Clark and I think of her as just as important as him. So there you go
.
