I find this hard to believe; I can wash an 8kg load and it takes me perhaps 15 or 20 minutes to hang it, and much less to unhang once dry. Folding and putting away is the same regardless of drying method.
EDIT: "just such a chore" made me think it wasn't about the drying time.
Also, why did line drying improve your sleep and reduce fatigue? This post is delightfully full of mystery.
You aren't supposed to wait there for the clothes to dry. They can dry on their own ;)
