Finish the lyrics, I can hold my breath
I can bite my tongue
I can stay awake for days
If that's what you want
Be your number one
I can fake a smile
I can force a laugh
I can dance and play the part
If that's what you ask
Give you all I am

I can do it

I can do it

I can do it

But I'm only human

And I bleed when I fall down

I'm only human

And I crash and I break down

Your words in my head, knives in my heart

You build me up and then I fall apart

'Cause I'm only human, yeah

Explanation:

I can do it

I can do it

I can do it

But I'm only human

And I bleed when I fall down

I'm only human

And I crash and I break down

Your words in my head, knives in my heart

You build me up and then I fall apart

answer; i believe the correct answer is "he who gladly serves"
