What are the positives of having two brains?

Some good things about having two brains:

• You can concentrate on doing 2 things at the same time.
• You can donate 1 for someone in need.
• If one of the brains gets damaged, you still have another one.
• You could be twice as smart, depending on whether you can get the brains to work together.
• Each brain could work with one ear, so you could concentrate on two conversations at the same time. (And talk to both of them too. Wow that would be a total mess. imagine each person talking to more than 1 person at the same moment!)
• You could sleep with one and let the other finish your homework at the same time.
• You could have great conversations with yourself.
• Someone would always understand your perspective.
