OP , it ' s probably best if you move out as soon as possible . If the arrangement and lease specified that no one could be involved in a relationship with a fellow housemate well , that just wasn ' t realistic in the long run . If the living situation no longer is comfortable for you , give notice and move out . <| sep |> Lord Jesus <| sep |> Halflives are 100 % something you use in physics . Radioactive decay is a random phenomenon in the first sense of the word which makes its modelling with halflives extremely accurate . The use of 2 as a logarithmic base is arbitrary , you could say that the same chocolate had a 111 hour don ' t quote me on the exact number fifthlife and it would mean the same thing . It ' s just a way to describe logarithmic decay using a somewhat concrete image . Interestingly , you can apply the same principle to interest rates with what is called doubling time . Instead of expressing interest rates in how much relative gain you make per unit of time , you can say how much time it takes to double what you had originally . It ' s the same information .
