spring cleaning?

So I googled spring cleaning today. Mainly because it's snowing in Chicago- I wanted to go for a long run on Saturday, but I don't want to be cold and wet. I was thinking that cleaning could count for decent exercise- but have you seen the lists some freaks have out there on what spring cleaning should include!?

Seriously, does anyone really do spring cleaning? Is it just some antiquated concept that my grandmother practiced, that no one does anymore, like darning socks?
