I didn ' t downvote you in the first place so you ' re asking the wrong person . Thanks for calling me snarky though ? Much appreciated . Assumptions are awesome , especially when they ' re wrong . <| sep |> Changing your DS time locks you out of timerelated events for 24 hours . <| sep |> Both ! Hmmmm ok something interesting . In tall buildings the sanitary plumbing stacks vertical pipes have arrestors in them to prevent the waste gaining velocity due to gravity after someone flushes a toilet . I ' ve been told could be a myth as I haven ' t researched it that there was an apartment building in Singapore where these weren ' t installed and someone flushed the toilet in the top of the building and by the time the waste hit the bottom of the stack the force cause all the drains and toilets on the ground floor to erupt .
