Meet the 1991 Life Expectancy Watch. I about fell over in 1991 when I found this. Know when you literally ran out of time. "A timepiece for monitoring and displaying the approximate time remaining in a user's life" Future feature of Apple Watch? http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&p=1&u=/netahtml/PTO/srchnum.html&r=1&f=G&l=50&d=PALL&s1=5031161.PN.&OS=&RS= …pic.twitter.com/3zsH0Zidcu
