Oxygen

You kept me alive, even when I was dying

you've been inside me even when I'm lying,

on my bed, caught up or lost in a dream 

Life without you, I wouldn't know what it'd mean.

Life without you, oh boy I wouldn't survive,

I would never know what it means to be alive.

If I miss a single breath, I'd suffer the consequence

I guess my body is nothing without you - oxygen.
