But to strenthen your neck you can put your hand on your forhead then press againt your hand. als do they same with each side of your head. and then do the same with the back of your head. Or do head spins like Pimple lol.
-------------- I must not fear.
Fear is the mind-killer.
Fear is the little death that brings total obliteration.
I will face my fear.
I will permit it to pass over me and through me.
And when it is gone past me I will turn to see fear's path.
Where the fear has gone there will be nothing.
Only I will remain
