Yes, I think the idea of a superpower being a mixed "gift". Initally, we focus on the benefits and only see that, but to every situation, there is advantage and disadvantage, and only by a bit more careful thought can we see that the initial rush of power is dulled by unexpected consequences!
I hadn't thought of being immortal! Imagine being there for all the important events of human history (past and future) and of all the time that you would have to learn all the mysteries of the universe! At the small cost of losing your loved ones over time...
