I make you weak at the worst of all times. I keep you safe I keep you fine. I make your hands sweat and your heart grow cold. I visit the weak but seldom the bold.

I work when I play and play when I work. What am I?
I am the beginning of the end and the end of time and space. I am essential to creation and I surround every place.
Every dawn begins with me. At dusk I'll be the first you see and daybreak couldn't come without. What midday centers all about. Daises grow from me I'm told. And when I come I end all code but in the sun I won't be found. Yet still each day I'll be around.
What never gets any wetter no matter how hard it rains?
