i have been a superman fan since i saw the first film when i was a nipper (im now 35) i then got into the comics and what not and the mythos of the worlds greatist hero gave me great plesure , joy and wonder. but saddly as the years roll on i drifted away a bit.i remember being enthralled at the fact that ,not only was superman invulnerable to harm under the earths yellow sun but that every thing from krypton shared the same indistructable quality .his cape, his suit and the metal from his ship could not be destroyd, which enabled him to shave combining his heat vision with the indistructable and reflective proppertys of said kryptonion metal he would burn the stuble from his face.but one thing has never been explained to me and this is my question WHO CUTS HIS HAIR? and by the way,if he can see through anything bar lead ,why(when hes dressed as clark) does he have to lift his glasses up to see through a concrete wall?if he cant see through clear glass then i am more super than him
