Good suggestions. I'd add another...eavesdropping on conversations. I do that all the time. Also watching folks at the mall. Don't do that much anymore, but when shopping with my wife, I eventually end up outside waiting...and waiting...so I watch people.

One more.

I make GITS my homepage, so I always start the day with movies.

@phil Eavesdropping is a great one. I find myself doing that all too often. I'll feel a bit guilty since stuff can sometimes be private, but it can't be stopped... Great list.

Some friends of mine made the mistake of doing the eavesdropping thing while in a biker bar. The bikers noticed.
