When I had a treadmill, I was of 2 minds about it. I did appreciate having it & being able to get some exercise but I didn't exactly enjoy it lol.

Blackout curtains: I've been on the fence about them. I kinda low-key want some for our bedroom, particularly the door that leads outside - but I'm trying to work out how to attach something because I like to open the blinds during the day [they are built into the door]. My body insists upon pitch darkness to sleep now.
