[Time Travel - General] What are some examples of the negative aspects of time travel that are never/rarely discussed in literature/movies/etc?

Dont drink the water and stay out of sight. 

I figured one of the hard things would be small changes compounding over time. Ever hear about an actor who forgets their original accent after putting on so many fake ones? 

I figure long enough time traveling would do the same thing. Your original timeline would be gone after a while. You could never go home.
