Too Much Information

A computer hard drive has a limited memory. I often wonder whether like a hard drive, a human brain can just simply run out of space. This causes me to question what I know. There are so many things in life people have told me which were wrong. So many people have bored me with information I just didn't need to know, yet I still remember it. The brain records every bit of information from birth, every image, every sound, every feeling, every taste, every smell.

Is there a limit to the amount I can hold in my mind? Am I about to run out of space? Should I be more selective about the information I take in?

Should I stop talking with idiots?
