How do I tell if a function is real-only, complex, or imaginary only?

If we could extend the human lifespan indefinitely, would our brains eventually run out of "storage space" for memories?

Say i want to learn piano or learn to draw but they would all take years (lets say 20 or so years) to master is there a way to cut that learning time in half so instead of taking 20yrs it only takes 10yrs?

If I crossed over the event horizon of a black hole, and fell towards the singularity but used a jetpack right before I reached it, that allows travel much faster than light (and say I can withstand the pressure), will I exit the event horizon at the infinite future? What does it mean for infinite time to pass?

So are fields just existing everywhere at all times? I.e a vacuum still has fields in it?
