Wow, this is kind of somber, but according to an article on Slate, there's a new website that combines the frequency of how often you currently see your parents, with the age of your parents; to predict how many more times you'll see them before they die.

SeeYourFolks.com was created by a team of British designers, and is based on standard life expectancy numbers. The team behind the site says they created it because, "we believe that increasing awareness of death can help us to make the most of our lives."

I'd imagine this website will cause an increase in holiday flights to see family this year.
