Revised Questions

What role does genetics play in defining our personality?

How does concussions in sports affect the game/people who play them?

How has social media affected how people receive news?

Your second question is such a controversial subject. You should really research this hard, because I used to play football and I have had a number of concussions this makes this topic very appealing to me. Dig hard for stats and informing regarding this subject, this could make for a really interesting paper.

This is a very good topic especially because of the recent Junior Seau incident and with how sports medicine doctors are cracking down with athletes and their ability to recover. Having had a concussion myself I know some of the problems it causes so I'd be very interested to see the results of this study.
