Most people try their hardest not to think about death in their day-to-day, but a review of recent research studies published in the journal Personality and Social Psychology Review suggests that when you think about death on a regular basis you actually lead a better life.
The review study looks back at a number of tests that have been performed over the last five years and found that when primed with the thought of death, either unconsciously or consciously, people are more likely to have a positive attitude towards others and themselves.
For instance, recent studies have shown that when you're reminded of death you're more likely to use sunscreen and increase your levels of exercise. Others show that you're more likely to help strangers and be nicer to people. Death isn't the most pleasant thing to think about and it certainly has its share of negatives, but before you go shutting it out completely remember that it can also be a powerful motivator.
