2 years till I can vote
5 years till I can drink

(not that i'm going to)
9 years till I can be a congressman
14 years till I can be a senator
19 years till I can be president
20 years till I can have conquered the world through nuclear diplomacy
24 years till i'm old
184 years till my bicentennial

about 5,000 years till the next ice age!
a few million (or was it billion) years till the sun blows up!
definitely a few billion years until all of the energy of the universe becomes to widely dispersed to support life and planets!
and then nothing notable will ever happen again!
