My heart will still beat

Who cares if I froze today
Sit until my body decays
Rest until my body's in a deep sleep
What does it matter if I lose everything
My heart will still beat
After everything
Even if I sit here all day
And all I do is freeze
Until my body can't make any heat
My heart will still beat
Who cares if I lose feeling
Who cares if I grow numb
After all I've become
Sit until I freeze
Losing heat
My heart will still beat
Continue on
Even if I freeze
The rhythm will repeat
