Paradox?
I have a couple of questions I'd like answers to:
1) Can Superman break his own finger? Since he's supposedly indestructible and Superstrong, what would happen if he tried to break his index finger or any other part of himself?
2) If Superman jammed adamantium into his skin, a substance which supposedly cannot be stopped granted the force behind it is unyielding, could he make himself bleed?
3) Does Superman feel anything? I've noticed he flies in fire, shoots beams out of his eyes, yet he's impervious to the pain this would normally involve. Can he feel the pain, yet tolerate it? Or does he only feel things to a certain degree and no more?
Both of the 1st questions are outside the possibility of having kryptonite nearby.
What do you think?
