I've just gone back to school to work on a PhD. My previous schooling was in the late 90s, before PowerPoint was used regularly in classrooms. This time around, I've had classes with older professors who use the chalkboard and young ones (younger than me) who rely on a presentation.

American drivers, in general, couldn't handle driving like they were in Germany.
