They're all more active than I am, but they all have good off switches and are easy to live with. They can go for hours, but none of them bug me for activity or exercise of any kind. They settle well, but are up and ready to go at a moment's notice. I like having high energy dogs, though... even if I'm not a go-go-go type of person. They keep me more active than I'd be otherwise, they're fun, and I just enjoy them. And all of the breeds I like are high energy breeds, so I don't really have much of a choice but to get out and do things with my dogs, haha. It'd be easy to get a big lazy dog who enjoys a walk here and there, but it really wouldn't be much fun for me.
