Without my cell phone

Unfortunately, without my cell phone, I wouldn't:

1. know what time it is
2. be able to solve a math question
3. know a single phone number
4. know the date
5. be able to text my friend when I am at their house
6. take a snap shot at a picture-perfect time
7. be able to wake up from an alarm in the morning
8. find my way in the dark
