Could you please help me with this?

Could you tell me if you could use JUST AS like this? and if possible give me a couple for examples ?

1 Just as there could be no fat in your filet, there also could be a lot. It depends on the cow

The wait to see a doctor could be 2 hours just as it can be 5 hours. I don't know what the wait will be.

2 How long can you continue this before you get caught. The average expectancy of a drug lord is a year before he gets caught. (how would you say this please?)

3 I wish someone could sing to me while I was drving./You could make me food while you are making yours./while you make yours.

thank you
1. equally possible

2. Sounds good.

3. am driving / other two are fine
Students: Are you brave enough to let our tutors analyse your pronunciation?
For 1, are say both are good?

How would you say them, something tells me you wouldn't say it like this?

thank you
It's fine.
