Radiolab did a podcast about this subject , they came to the conclusion that one thing that ' s happening is people are accidentally pushing the accelerator when they think it ' s the brake <| sep |> So its like being high on coke <| sep |> And America thinks Trump is bad <| sep |> Nope , I just made it <| sep |> As my mom used to tell me I brought you into this world , so I can take you out also . <| sep |> I can give a really specific answer to this , as when we got our new boiler a few years ago it came with a thermostat with a 7 day programme and I ' ve never bothered to tweak the defaults . I just leave it on these settings 365 . 24 days a year , in the summer the boiler never needs to come on to maintain these temperatures so it ' s always a bit of an event in our household in the autumn when the central heating comes on for the first time Oh ! The boiler just came on ! . I ' ve just copied this out of the manual from the Worcester Bosch websiteMonFriTime Temp C 0630 200830 161630 212230 7 SatSunTime Temp C 0700 200900 181200 211400 181600 212330 7
