Oh wow ! I really like your explanation , it seems to make a lot of sense to me . Thanks ! In my analogy , I guess that would kind of be the equivalent of prions digging into the Earth to make the hill even longer , rather than pushing the boulder back up the hill . I ' d be interested to see whether misfolded proteins caused by prions are in a higher or lower energystate than their native conformation . <| sep |> Goodness , that runny nose example is amazing ! <| sep |> The interrobang has the exclamation point on the left part of the question mark , and left on center of the character overall . If ? ! were closer , you ' d have a bit of the exclamation point hanging down off the curve of the question mark and then two dots below it .
