Impulse Kickstarter Purchase: Tikker

I bought an awesome watch today.  It's called the Tikker.  The Tikker tells time and includes a multi-year countdown timer.  You calculate your expected lifetime from actuary tables and program the tikker.  It gives you the current date and time, and your remaining projected lifespan.

I know it seems kind of morbid, but how awesome is this?  What else could remind you of the value of your time like this?

This pleases me.
