Forum:Smeagol/Gollum aging...?

Question! When Smeagol obtained the one ring from Deagol he became corrupted by its power and subsequently banished from his relations. My questions are why did Smeagol fall under the evil of the ring when Hobbits are good natured? Is it because of this evil that transformed his physical appearance, when Bilbo and Frodo when in possession of the ring do not age at all? Or is it because Smeagol decided to live in the darkness of the Misty Mountains that he changed? I am clearly reading too much into this but if anyone can help I would greatly appreciate it!
