sleep for a week

My boyfriend has a band that goes around the wrist and measures all kinds of clever things like pulse, and can apparently work out the kind of sleep patterns the wearing goes through. I borrowed it last night tho the battery ran out part way through so the data isn't perfect. I don't really like having any restrictions so don't wear anything like a watch or rings (not even by day any more) so I think it will have impacted on the results anyhow as I was conscious of it. But I am interested so might ask to borrow it again another night. Not tonight tho, as I will be in a different bed and never sleep so well in a different sleep environment. Tho it is Dufton, one of my favourtite places in the universe, and so I'm hoping to find the weekend restorative :)
