Anyone for a hug?
"Imagine a prescription which prescribed four hugs per day to a patient suffering from depression. Hanning described findings that four hugs per day was an antidote for depression, eight hugs per day would achieve mental stability and twelve hugs per day would achieve real psychological growth. If this is the case, touch has a greater significance than most of us would realise."
