How do we know when we have reached our limit? Rattling up, firing from all pistons And it seems like you can't go there And it seems like you can't focus Focus oh-oh When you're running on empty And it seems like you can't breathe Don't got no more energy I'll be there when it runs out I'll be there when it runs out I'm your reserve I'll be there when it runs out I'm your reserve I'll be there when it runs out I'm your reserve I'll be there when it runs out I'm your reserve How could you know, telling me what you're made of? Saying it loud, but you still have not proved me wrong It takes more than some gas to start a blaze You need something within you to ignite the flame Come on, give it to me now And it seems like you can't go there And it seems like you can't focus Focus oh-oh When you're running on empty And it seems like you can't breathe Don't got no more energy I'll be there when it runs out I'll be there when it runs out I'm your reserve I'll be there when it runs out I'm your reserve I'll be there when it runs out I'm your reserve I'll be there when it runs out I'm your reserve I'm your reserve I'm your reserve I'm your reserve
