The conclusion drawn was everything affects us in the environment. Another study was done based on is you hold a cold or warm object in your hands can they change your decisions.
As a therapist I sit in a room talking to people and I watch where their eyes go when they are talking to me and they dark major places. Once I saw that, I went onto word and I wrote messages I wanted them to see then I printed them out and I taped them exactly where I saw their eyes dark.
Use everything to your advantage.
