Life is relatively short, although life expectancy depends on what country you live in, and is longer in the first world. Many people, when they get to their golden years, suddenly realize there were plenty of things that they didn't get to do that they would have enjoyed doing during their short time on Earth. But the greatest thing we all wish for is that we had spent more time with our loved ones.
Yes, life is short. When one considers that the Universe is billions of years old, the scant time that humans are allotted life is disheartening. The entire human race has been around only a couple hundred thousand years, and our lives are only a fraction of that time. Life is short, indeed.
