Aging Astronauts

I count the stars almost every day,
the aging astronauts have floated away.
I watch the future from the edge of a knife,
the same stars that killed you will bring you life.

Will you go on without your friends?
There's a time for everything except the end.

The same future hasn't got the same past.
You've seen the good times, BABY can you make them last?
I ride a plane almost every day,
I've seen the freaks lost in the Milky Way.

Will we go on until the end?
I know it's coming, but I just don't know when.
