We've had a Netflix account for years. Recently, I created a couple of different user profiles on the Your Account page. I use one of these for educational type programs (they've got all kinds of Nova shows along with documentaries and stuff on science and math and music) and the other is for exercise videos (yoga, tai chi and dance).
Obviously, I could just add these types of shows to our main queue, but I like to ensure that there's always one exercise video and one educational video around most of the time.
Jeff, my love, I would ask here that you don't chime in with how long I actually keep these movies at our house. Thanks.
If you don't already have Netflix, I'm not suggesting you sign up just for this because the library is also a fantastic (and free) source of this type of material, but if you already have an account, it's pretty handy. There's lots of good stuff there if you look around a bit.
Sun Salutation Update- I've done 4 of these for yesterday's comments.
