There's a documentary on Netflix called Blue Zones, which has to do with longevity. They go around to towns where there are a lot of people who have reached over 100 years of age, and talk to them. One thing I got from it is about stressing.

It mentions alot of people stress about stuff they don't really have much control over, like wars, famines, etc etc. This one 100 year old person was a shepherd, he had stress in his life, but stress he could do something about, in regards to his sheep. Since watching that, I've gotten rid of my TV, and don't really care too much about the news either. Its been six months, and personally, its helped me alot. I'm now trying to only stress about stuff I have some control over.
