There are no unlockable doors.

There are no unwinable wars
There are no unrightable wrongs
There are no unbeatable odds
There are no believable gods
There are no unnameable name
There are no impossible dreams
There are no invisible seams
There are no uncriminal crimes
There are no unrhymable rhymes
There are no identical twins or forgivable sins
There are no incurable ills
There are no unkillable thrills
There are no unachievable goals
There are no unsaveable souls
There are no indisputable truths
And there ain't no fountain of youth.
