Unit 3-Brainstorming!!!

Hey everyone, I would like to know if you have an opinion on either of the following two topics:  Depression and its effects on adults and children are they different? or Eye cancer and metasis is there a cure?  Please let me know what you think.  I am leaning towards depression because it links with my paper due in anatomy and physiology and because I suffer from depression, but the eye canncer touches close to home because my mother-in-law was diagnosed this past January with it and it has spread.  Both topics I think would be interesting.  Whichever one I don't use this time I am sure I will use in another class here at Kaplan.  Please give me some feedback.
