Proof That Altering Timeline Is Impossible

1) None of my descendants have gone back to the Bronx in 1993 and persuaded me that taking Russian to fulfill my college language requirement is a terrible, horrible, no good, very bad idea.

2) No one has gone back to Florida in 2000 and informed someone that maybe this butterfly ballot is an even worse idea.

At any rate, congratulations to Al Gore and the UN scientists who have won the Nobel Peace Prize this year.
