Riddles:
1-A woman is put in a cement room without windows. The door is mechanically bolted shut and under strict watch so that nobody can come in or out. It is secured in every possible way. 24 hours later, the door is opened, and there are now 2 people inside the room. How is this possible?

2-I run through hills; I veer around mountains. I leap over rivers and crawl through the forests. Step out your door to find me.
What am I?
