Agreed for sure.
We are what we let into our minds..bar none.
Just like what we choose to eat---a nice organic salad or a Big Mac changes the chemical reactions in our body that cause toxins, sickness and disease--what we let into our ears and eyes also does the same.
I also try to avoid these movies as much as I can.
I like happy, upbeat movies that make me smile and laugh.
But, it all comes down to how you percieve the movie--if you do choose to watch these kind of movies.
If you enjoy Horror movies--then dont avoid them--they will not cause you to die sooner. This is all as long as you treat the movie as a 90 minute escape to just enjoy the suspense and theatrical creation--as opposed to most who become so stressed out from it that it will make them acidic, and they cant sleep until thet can once again relax. In that case--it may cause health problems for some.
Bottom line is....Think, Eat, Speak, Watch, Hear and Do those things that are inline with keeping you healthy both physicall, emotionally and spiritually.
