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.
