If I had a magic wand with which I could change any three things about the present world, I would:

1. Create absolute world peace, forever. Probably, this would have to happen by removing the majority of men in power of various authorities, like governments and educational institutions, and replacing them with well-educated, liberal women.

2. Distribute free chocolate to all PhD students, worldwide. And…

3. Make all men disappear…at least for a little while.
