Fight outta you

I was listening to Ben Harper & The Innocent Criminals' song "Fight outta you".

There's always someone younger, someone with more hunger, don't let them take the fight outta you
They'll say you're the one and only
Then straight up leave you lonely, don't let them take the fight outta you
Like a transplant-patient waiting for a donor, don't let them take the fight outta you
Like a half empty balloon after a party in the corner, don't let them take the fight outta you

Be strong, friend.
