14,610 Days Behind Me...

may-21

... And hopefully a similarly large number of days ahead.

On a related note, I decided to give Wolfram|Alpha a go at figuring out how many days since I was born.  So, I plugged in "may 21, 1969" to see what it would come up with.  Besides the "no known notable events" notice -- thanks, you're lifting my spirits -- it also told me my date of birth was both 39 years, 11 months and 31 days ago as well as 40 years ago.

Perhaps it's rounding off?  At least it got the number of days right.
