who envies who?

i was watching Troy on tv last night when one particular line Achiles said to Breisies kinda got me wondering. It goes, "The truth is that the gods envy us mortals. The fact that one day we will die makes each moment we have so much sweeter, while they are forever immortal." Its strange isn't it? In the light of what he said, it makes us seem so blessed that we have chances to make moments more special than they already are just because they won't come again and we won't have the chance again. And yet we do envy the gods because they are immortal... Wait wait, don't tell me no, because you know that's a lie. Maybe we've been doing it unconsciously, like in our quest to remain forever young. Each of us wants to stay young, beautiful and radiant. But is it really worth it? The gods envy our fleeting moments while we envy their lasting presences... Quite a paradox ain't it?
