"I store things in a place that has no address you can visit. I exist everywhere and nowhere. Lose your device but never lose me. What am I?"

I speak without a mouth and hear without ears. I have no body, but I come alive with the wind. What am I?

The taller I am, the younger I grow. The shorter I become, the older I am. What am I?

I have a bed but never sleep, a mouth but never eat. I run all day but never tire. What am I?
