I’m interviewing my brother about his life and his childhood and at school and ask deeper questions about his life and his childhood and at school. i’m interviewing my brother

Okay, hopefully, this helps:

What is your biggest regret, and if you hadn't done whatever that is, how would your life be affected by this?
What is your deepest aspiration?
If you could solve any problem in the world, what would you solve? 
What is your fondest memory of childhood?
What memory (this can lead from the previous question) has affected your life the most?

Ya, i would say almost the exact same thing as the person who answered before me. So there is no reason for me to repeat it would suck for you.

Yeah, things like gatorade with lots of electrolytes.
