This is a game like thing.
It can be any problem, no medical problems, I doubt that anyone on this forum has a PHD but i could be wrong.
example:
User A: I cant figure out how to make a potato explode in the microwave, what to do?
User B: you dont poke holes in the potato, it shall explode then. [insert a new problem]
problem: My two friends hate each other, i have no clue what to do.
