Dead At Your Age (hat tip to shatterstripes):

You are 23 years and 266 days old today.

That’s exactly half the life of somebody famous. In another 23 years and 266 days, you will have lived exactly as long as Fernando Pessoa. He was an innovative poet and creator of heteronyms, imaginary characters who write in different styles [sic] who died at the age of 47 years, 170 days of cirrhosis of the liver.

Fernando Pessoa lived twice as long as you have, but other notable people have died at about this age.
