I always open the refrigerator to think

Well, probably the cooling effect of the fridge eases more neurons to flow and that makes you think. :) We all have ways (it may be funny) to think. Have you ever asked yourself why or when did you start doing that? there may be some psychological explanation. Probably a turning point in the past. There's nothing wrong to it. Im a kinesthetic learner. I move to think, to store information, and to retrieve them. Let's open the fridge more. :)

I think before I open the refrigerator! siva

i open my refregerator to think what i need to prepare for my breakfast lunch or dinner or for tomorrow.

Makes sense.
