A lot has changed over the past decade, including our temperament...perhaps because of the polarizing 24-hours news cycle.
UTMB professor and psychologist Dr. Jeff Temple said we tend to have a Pollyanna view of our past and pessimistic view of our present.
"There is this 24/7 news that does make us feel a little bit angry, and when we feel angry, we want to fight or flight," said Temple.
He said depending on how anger is channeled, it can have a negative effect on our health.
"It think that this 24/7 access to news, to social media does paint a bleaker picture of what the reality is," said Temple.
He said anger isn't necessarily a bad thing--it can be motivating and used constructively and for good.
